The other day, I was looking at the Twitter stream of an acquaintance of mine and I clicked on the username of someone he was talking to. I opened that person’s website and I found myself thinking, “that sounds familiar.”
It took me a while to place it, but then I realized that the person was a spammer. Or, at least, they had spammed my community previously. They had joined in 2007 and posted a few spammy messages, even going so far as to encourage people to click ads on his site or commit click fraud, as it is commonly called. I removed the messages and banned the account.
