We've all seen what I call the evolution of spam in-game. First it was just straight tell spam. Blizzard fixed that. Then it was group spam. Now it seems gold farmers have taken to just sitting in the capital cities and screaming their lungs off until they get reported and/or zapped by a GM.
I think the reporting mechanism is starting to get to them though. Every time they lose an account (when it's reported) they have to make a new one. In the scope of the money they're making it's really not a big deal, but it's tedious repetition and I saw the first signs this morning that they've shifted their focus and are moving to more aggressive tactics.
I fired up Adium (my Mac instant messenger) and was immediately greeted by a request for contact authorization. I'll stop here for a moment so you can gasp, because what happened after this is exactly what you think. I looked at the address that was requesting authentication and it didn't really ring a bell. I looked at the display picture and saw a cropped screenshot of two blood elves staring back at me. I reasoned that it had to be someone from my guild, even though I wasn't sure who. I accepted the request and the contact appeared on my contact list. As it turns out, they were online.
