There is a Minecraft Server exploit circulating the last few days allowing players with temporary or permanent bans to circumvent the ban. As with any exploit, use of such an exploit is a violation of the EULA and Terms of Service. Violations can result in an immediate and permanent termination of posting privileges. Also, use of this exploit by a permanently forum banned account can result in actions being taken against the user’s ability to play Squidwolf Minecraft, up to and including a game ban.
The Dev team have been made aware of this exploit and are resolving the issue.
