I accidentally voted down for something for my brother in my account, and then switched to his account to comment. Am I in trouble now? The save was called "pokemon ditto". By the way, this is not just a necropost. I thought it would be a good idea to post here for convenience.
@me4502 Asking cctvdude99 how he got banned won't work, he is banned. You'll have to wait untill he creates a new account... that's probably what you were thinking. It was quite a surprise to me. Maybe there should be way to stop your own IP address from voting for its self... I'm not sure if this is possible, I wouldn't know.
At any rate, making multiple accounts isn't really a big deal. We can pretty easily tell when a save's had multiple votes on it from the same location when it becomes popular, so it's not something to fret over.
