Of course, there are also simple ways to reduce receiving spams.
1. If you have a website, hide your e-mail address from spammers by using Unicode characters -or- use something like this:
yournameREMOVETHIS@domain.com
E-mail address encoders should be Javascript. Unicode can be read by spammers using latest technologies. Just like search engines, they improve. Go to the ff: site

2. Never post your e-mail addresses online especially on message boards. If it's necessary use an alternate e-mail address instead like Yahoo Mail because it already have a bulk mail feature.
3. Do not reply to spam or buy anything from spam e-mails. They will just know that your e-mail address is legitimate and will just be sold away to other spammers, thus, you'll receive more spams. Tsk tsk.
4. Also never unsubscribe. See No.3.
5. Instead of putting your e-mail address on your website, use a Formmail instead. Astahost, I believe provides that sort of pre-scripts. See your Cpanel and Formail. That will help a lot.
6. You can also use a temporary e-mail address just in case. Good ones are Mailinator.com
7. If you are really tired with the hundreds of spams you receive, use an e-mail filter. There's a lot of free ones on the web. Search on Google.
Note that if you use e-mail addresses of the big ones like Yahoo, Gmail, Hotmail, AOL, Comcast, etc. you'll receive spam no matter what. Even you just made a new e-mail address (I have a new gmail account, never propagated to anywhere, but I still receive spam). Very few people knows exactly how spammers harvest addresses. Just like the mystery of Google search engine optimization. That's technology.
But if you use your own mail address from your ISP or your own domain name, take advantage of it. I had been careful with my e-mail address and from 2 months until now, I received zero spams.
Those are simple things you can do. It's not that hard so if we all cooperate, we can stop spam. However, spamming on forums is another story...
If you have any other ideas you want to add, just add it here. Many will appreciate it.
