Multiple different accounts were created and used to upvote his own stuff and target other users with downvotes. This is the second or third time a user has been banned for vote manipulation, and as far as I can remember, the only reason aside from spamming that a user has ever been banned. Please do not create alts for the sole purpose of giving yourself more internet points, it's pointless and we will be able to find out if it's happening.
In the future, we could implement account restrictions to try and curb this. Currently we have no restrictions on freshly created accounts, other than sub creation and captchas for posting. We could maybe add up/downvote restrictions based on age of account or account level.
But yeah, thought it would be best to make a note of the banning rather than explain what happened in a couple of weeks if someone asked where he went.
PS: No, the irony of making this post on an admin alt is not lost on me.
I noticed from a comment in one of the other threads that this site allows new users to downvote immediately. I'm not sure if you are the OP or an admin, but isn't that asking for trouble? I mean someone could post 100 pepes and upvote them to spam a board to try to force moderation, I guess but the downvote is far more powerful given that it could hide content from the typical user who doesn't browse new and so being far more tempting to those opposed to the posts in question. So, that said, if you site founders here don't want to remove the ability of new users to downvote maybe you could look at removing the ability for posts to be hidden by downvotes or possibly use a different metric to determine which posts are seen by default that posts count. Maybe total votes or controversial could also be shown.
@polsaker @pembo210 - apologies to any other admins I missed.
Not really looking for a discussion here I'm just throwing some ideas at the wall that you can talk about amongst yourselves or not.
