On my server there are three «Lost», two «DT», a billion «Blood», and I recently discovered my own FC tag was recently copied. It causes a lot of confusion, because these tags are what people see first. A lot of them assume the tags are the same FC, but they aren't. Which then runs into reputation issues, etc.

I think it'd be great to have a system where tags cannot be replicated, just like how retainer names can't be. You can change the tag whenever, but no multiple ones should be allowed on the server. I understand this can cause some issues with dead FCs that have all the good tags... but still. I'd rather have to come up with a more unique tag than see 4 different FCs with the tag «Blood» running around and thinking they're all from the same FC.
