A few butthurt idiots (it's like the same 3 people) pay $10 to go on a 30 minute spam spree to try and get back at someone they just payed $10. This happens like 4 times a year?
It's the stupidest stuff in the universe. It doesn't damage anything. If you hadn't noticed, people just start ignoring it/blocking it and the day goes on like nothing is happening. Then a short while later a moderators comes and with the click of a button it's all gone. A fine use of $10.
