This morning, I found this comment in the moderation queue.
hello , my name is [omitted] and I know you get a lot of spammy comments , I can help you with this problem .
I know a lot of spammers and I will ask them not to post on your site. It will reduce the volume of spam by 30-50% .In return Id like to ask you to put a link to my site on the index page of your site. The link will be small and your visitors will hardly notice it , its just done for higher rankings in search engines.
Contact me icq [omitted] or write me [omitted](at)yahoo.com , i will give you my site url and you will give me yours if you are interested. thank you
So, he knows up to half of the spammers that spam my site – besides himself. In exchange for his service, he wants me to participate in SEO spam. Hmm.
No thank you, I’m not interested, i will not give you my site url!
