Tell me how much spam you got, I'll tell you how much your site is well indexed
Recently I was receiving lot of spams, it started with the old publishing plateforme and is continued with the current one and even going higher. This have been in both comments and trackbacks, and looks like the trackbacks attract more spammers. What I was looking for is how do the spammer bots find my website or pages that they are spamming ? After few investiguations I found the referer source and it was search engine.
The approach is very funny, specially that spam is really annoying in big website offering interaction like comments and trackbacks, hopefully nothing else. I won't talk about this as a way to report performance of your search engine optimization but it was an excellent indicator specially that spammers start their searches from precise keywords in search engines.
This will give you also information about the negative point of Search Engine optimisation which is being easy to find for spammers. And this is not really a negative point because we have find lot of solutions and techniques to stop all these spammers. The most easy technique is to use htaccess for example by setting list of banned urls
SetEnvIfNoCase Referer .*poker.* ban
Then add a Files section with the following setting
Order Allow,Deny
Allow from all
Deny from env=ban
This way you can define all bad words keyword to ban. The only problem here is the spammers that use common words, unfortunately you have to add them one after the other for example
SetEnvIfNoCase Remote_Addr ^219\.84\.70\.108 ban
I use the IP because in most cases they have more than one domain in a shared hosting, this will ban everybody.
