one way that i cut down on spam a lot is by blocking the whatever.whetever of the spam addresses
Some of them are from yahoo and hotmail accounts, but ones that are something like
whatever@23fht3s.net can be blocked, and you wont' get any spam from any of the spammers at that account, as well as the asshat who sent it.
It seems to cut down on a lot of spam, but if you don't keep up with it, you will end up with the same amount of spam in about a month.
I think it's strange that even having your email address on your own site from your own server, you still get spam.
I had a site up for a while, and i didn't give anyone the address that i had on the website. It was
support@mydomain.com, and i got a shit load of spam on it. The only place that email address was listed was on my site.
These spammers must be getting smart by taking google search results, then crawling pages for email addresses. I would do that it i was a spammer, or making money off of spammers.
either way, spam is annoying and i'm just waiting for bigger laws to come into play regarding spam.
