I found a unique way to fight email spammers and waste their time
"This page has fifty randomly generated email addresses (refresh and new ones will appear). At the bottom of the page is a link to this page again, essentially reloading it for programs to collect more fake email addresses. Email collecting programs (spam bots) will be sent into an infinite loop by following the link at the bottom of the page and will get more and more fake email addresses stuck in their databases."
What a convenient way for such a website to get back links. Totally ethical and unspammy of them as well. As a blogger and affiliate marketer who rarely encounters email spam, the main annoyance I've seen is blogspam and spam on forums. (Blog spam is a term that's often used to describe any spammy website.) A common way of fighting blog spam would be when a moderator chooses to shadow their posts, or even shadow ban the user (they can still log on and see what others are saying, but only they can see the posts that they make). Another good technique to waste a spammer's time, although this is often used by unfair moderators, or by an unfair built in algorithm of the forum (in other words it might not be based on a decision made by a person, but instead certain keywords were detected over time etc.)
