There is no need to create a rule that says don't abuse the system. Everyone who was involved knew he was abusing the system. Unvoting massive amount of posts isn't something you do without any reason.
To some degree I guess it was my own fault that I didn't recognize that loophole.
Maybe some users who are actually supporting the platform were caught in the middle of the blacklisting.
Thats why I give everyone a chance to redeem himself. Upvote and curate content for the next two weeks on dMania. Upvote fair and without any intent of selfishness or abuse.
In two weeks I will check the vote distributions of the users who were blacklisted and If I am satisfied I will remove them from the blacklist.
