I use a WYSIWIG web editor (such as Dreamweaver, FrontPage, PageMill, Microsoft Word, etc.) How do I insert the MWMW.com Munger code in my editor?
MWMW.com does not offer technical support for individual WYSIWIG (What you see is what you get) web editors.
Most WYSIWYG web editors have an option either to work in a "code window" (as opposed to a "design" or "layout" window), or an option to insert a "custom" tag. See if you can find and use these options. You may wish to contact technical support for your specific product, or ask in a user discussion group or forum devoted to your product.
Code for the MWMW.com Munger can also be manually entered outside the WYSIWYG editor using a text editor such as Notepad, SimpleText or vi (depending on your operating system).
Can I use the MWMW.com Munger to link an email address to a button or other graphic?
Yes. Copy the HTML img code that displays the button into the "Link text" field. For example, the image code to display a button might look something like this:
<img src="graphics/contact.gif" height="20" width="100" alt="Contact us" />
Copy everything from (and including) the "
<" through the "
>" into the "Link text" field. If your button has rollover events (
onmouseout), copy those into the Link text field as well.
<noscript></noscript> tag might have this format:
What is munging? Why should I do it?
Unsolicited commercial email (UCE), also known as spam, is a serious problem. Many businesses use unscrupulous practices to add email addresses to mailing lists. One of these tactics is address harvesting. This involves using automated tools (called "address harvesters" or "spiders") to retrieve web pages and extract email links from the text. (This is similar to the techniques that search services like Google use to index web pages.)
"Munging" refers to any of several techniques to conceal email addresses from possible spammers.
There is an excellent detailed discussion of munging at the Project Honeypot site. Project Honeypot is an anti-spam initiative designed to trick address harvesting programs by feeding them specially-flagged phony email addresses.
How does the MWMW.com Munger work?
The email link is visible! Can't spammers just load the page manually and read it?
Yes. If you have an email address that you're trying to completely hide from spammers, you might not want to use that address on a page. However, the economics of spam rely on low costs to the spammer -- because the margin is slim, and returns get smaller and smaller as more people wise up. It's cheap to write or buy an address harvesting program; it's another thing entirely to pay someone to sit and load web pages all day long. In general, spammers are highly unlikely to load your page, read it, and store your email address.
I'm already getting a lot of spam mail delivered to my domain. Will this help?
In the short term, no. If your address is already on spam lists, you will continue to get spam. I don't expect you will see any immediate improvement.
In the long run, probably. The utility of an email address list decreases sharply over time as people change their emails. If you use MWMW.com Munger, your email address will not continue to be indexed. Eventually the volume of spam you receive should decrease as spammers purchase and use new lists that no longer include your address.
Can I reduce the amount of spam I get by changing my email contact?
Yes. For example, if you currently have an email link to "email@example.com," we can set up a new alias using the MWMW.com Munger, for example "firstname.lastname@example.org."
However, there are a couple of concerns you should be aware of:
- In most cases, you won't want to disable the old email address because your current customers and other contacts will continue to use it.
- Harvesting is only one of the techniques that spammers use to create email lists. You may also be vulnerable to "address guessing." Spammers may simple assume that certain user names probably exist -- like "webmaster," "info," or "sales," but also like "steve" or "ajones" or "dsmith." You may want to consider using less common terms or a firstname_lastname format to reduce the risk of having your address guessed.
I have the same email address links on several different pages. Do I need to use the MWMW.com Munger for the links on each page?
No, you can use the MWMW.com Munger once to generate the code, then insert it into as many web pages as you need to.
What if I have more than 5 different email addresses on a single page?
Munge the first five addresses to start with, and insert the code into your web page as specified. Then munge your additional address, but change the numbers 0 through 4 to 5 through 9. For example, change
Can I use the MWMW.com Munger from other web sites? Can I keep using the MWMW.com Munger if I terminate my contract with MWMW.com?
No. This feature is offered only to current MWMW.com customers, and only for web sites hosted directly on MWMW.com's servers.
<noscript></noscript> tag will be presented. It is important to ensure that your visitors will be able to interpret this information, but you may want to be cautious about the format you use to present it.
For example, when address harvesting first became an issue, some web designers responded by formatting addresses as
myname -at- mydomain. Unfortunately, as soon as this technique became common, address harvesters were modified to identify addresses in this format, swiftly reducing its effectiveness.
The MWMW.com Munger creates a
<noscript></noscript> tag by default that uses an alternate representation of the characters in your email address. For example, the character "@" will be replaced in your web page by
@. This format should be difficult for most address harvesters to extract, but it is not totally secure. You may want to customize the
<noscript></noscript> tag, especially if you are linking your email address to a graphic. Other possibilities for
<noscript></noscript> including simplying displaying a message to your visitors:
or providing a link to a page on your web site that provides another means of contacting you (such as a comment form):
<noscript><p>To contact us, please use the <a href="comments.html">comments form</a>. </p></noscript>
Please note, as discussed in the disclaimer, that you assume all risk from the use of this software, including (but not limited to) any potential damages arising from interrupted or failed communication attempts.
My page fails validation after I insert your code. How can I fix that?
Strictly speaking, a
<noscript></noscript> tag should not appear in a block-level element like a paragraph, so if you have an email link embedded in a paragraph, you may get validation errors. In practice, mainstream browsers allow this error, and MWMW.com has attempted to simplify the MWMW.com Munger process to meet the needs of clients with varying degress of technical knowledge.
If your site requires strict validation, there are two techniques you can use.
Include the relevant block-level element in both the
<script>tag: "Email us at email@example.com for more information."
- Separate the
<script>tag: "Email us for more information." This visitor will also see the additional paragraph in the
<noscript>tag, "Please use our contact form to submit an inquiry."
I'm using MySQL, PHP, or other dynamic content on my site. Can I still use the MWMW.com munger?
Yes. Simply include the code generated by this page in your PHP script, included documents, or database records as necessary.
Won't address harvesters figure out how to descramble my addresses?
This is possible, but MWMW.com believes, highly unlikely.
To broaden a search for
firstname.lastname@example.org to include
name -at- domain.com is extremely easy with pattern matching techniques like regular expressions. To identify and reconstruct an address stored in a scrambled format is much more difficult, and it would result in a much slower -- i.e., more expensive to run -- harvesting program. Additionally, if a web site developer has gone to the effort of concealing an address from harvesters, that address is less valuable to the harvester because the recipient of the email is likely to be sensitized to the problem of UCE, will be resistant to email which arrives despite any filtering that may be in place. MWMW.com believes this more work/lower return balance will discourage address harvesters for the foreseeable future.
