Is it spam if it’s a man made comment though? I don’t really mind someone having their link in a post as long as you get some actual human interaction out of them.

Lately what I did was remove the links out of a spammer’s bot comments so that my site would rank for his keywords (Not that I was interested in them, but to spite him) Of course the bot interpreted it as an open blog so I received a bunch from the same source immediately after so I had to blacklist it. Still left the url stripped ones though 🙂
