This Friday, The Elder Scrolls Online announced bans relating to Tales of Tribute exploit.
In addition to the announcement below, players have been warned that the developers will be monitoring the logs and any one found exploiting this bug before the hotifx on Monday could face a permaban. Banned players have been notified.
We recently discovered an exploit involving Tales of Tribute where performing certain actions would guarantee a win by forcing your opponent to forfeit. We are working on a hotfix for this as quickly as possible, which we are currently planning to publish on Monday. In the meantime, we have banned several game accounts that were found to have clearly abused this exploit in extreme excess; we have not banned any accounts that may have unintentionally encountered this bug.
