So I was looking through the Akismet spam bin to see if anyone’s posts had been erroneously caught, and noticed that the spammers started something new. Now spammers were posting droves of messages to .edu wikis as their urls, talking about some pain meds. Then a few hours later they dive in with messages like “i got the same XYZ attack on my blog too. I did XYZ” and their links seem innocuous enough, but turns out their urls pointed to similar competing online pharmacy operations!
A less astute webmaster would have approved the messages (had the counter spam not been flooded as well). So spammers, if you want to get in, don’t flood sites like that.
