Quite correct, Thallen. Spammers have taken to using bots which harvest
mailto: links. They then spoof their junk as coming from addresses in the same domain, or addresses acquired from the same page, as yours. One very simple workaround is to obfuscate your email address, like, say, growlz@
[email protected]. People will easily be able to replace the blanks, but spambots don't dedicate the CPU time to doing so.
Of course, this won't help you if you're already on their lists. All I can recommend for that is getting an email program or provider which offers fairly good filtering.
