Forum spamming tolerance

Today I just found another spam post.

hi dear all

i have to need the help for give me Idea for Google Adsence

Thanks

That person says he's from USA, but his English is worse than mine! And I am from Slovakia.

The questions is: Allow forum spammers or ban them? However, that forum where I found the above-mentioned post doesn't allow a forum administrator to ban people! Weird? It is NOT!

The game is simple to understand. Man acts to be an SEO expert. Later he realises that he can't earn money with AdSense on his forum (which isn't his own -!- and he just downloaded it because he probably doesn't know any programming language) because forums are full of spammers and links builders so he starts a directory. Of course, paid one. No-one knows if generates any profit (reasonable profit of course), but he still acts as SEO guru.

And such person allow spammers to post stupid questions, stupid answers, etc.

You could ask what is the point of this post... It is simple.

If you are doing serious business, don't allow questionable human beings to spam or hurt it! One of my sites which is getting about 1500 visits each day would be spammed with low-quality messages. Do I allow it? I do NOT! Moreover I created a strong anti-spam filter which catches 100% of spam. Do I store and read those spam messages? I do NOT!

Spam and spammers are evil. Whatever you do on the internet, avoid spam.

Spam makes people disappointed. Who is interested in spam posts? I am NOT
