Back I'm banned for "multi-accounting", what's that about?
If you are banned, and the reasons says "multi-accounting", you are suspected of upvoting a set with multiple accounts, this is strictly forbidden. Most of the time you will be banned for two months.
We won't reveal all methods that the moderators use to detect illegal votes, but the most common reason for people to get banned is because multiple votes are done from the same IP address.
If you think you're banned unjustified, provide us some proof that the votes weren't done only by you and we'll have a look at it.
