This website bug duplicates the name of the player in the clans page... I saw the clan cro and whaley's name appeared 2 times in former members list.
I think that is when a person is charged for multiple accounts, and then their other account is deleted, replaced by the account that was requested to be kept.
I got this from when JiGz got banned, I saw two of him in the |-210| former clans list. That wasn't there before he was banned, the first JiGz was his second account, Go0n.
It might be wrong, just my statement.
