Every discussion about improving the forum or protecting it's members is useless, as long as idiots are allowed to create countless forum accounts. It's like fighting against Hydra.
Well everyone is a member with the same rights and I think more as the half of all Forum Members have more as one Account.
There is no way to limit Accounts in a Public Forum.
For a Account Limit is a closed board needed and then is it possible to give all paying members one Access but this will also not Fix the problem because many many Members use also Multiple In-Game Accounts
