If you’ve been on these forums for the past 4 years, then surely you must have been aware of the fact that all members are typically affected by bans on a single clan member’s actions. This is nothing new. Also, you surely must be aware of the fact that PvP servers are rampant with false claims or claims over something petty. Joining a clan with people you don’t know, and doing it several times on several servers, is absolutely your fault. Unfortunately, you’re a victim of the system and a victim of trusting people too much. It sucks and you shouldn’t be punished for it, but there are preventative measures that can be taken if you find yourself in that position again, assuming you can get your ban appealed. Nothing you can do about servers you don’t remember though, short of trying to log into every server in your region and seeing if it loads you in, or you’re taken to a character creation screen. If you get the former, leave the clan or delete the character. Tedious, but simple in theory.
