Just here to revive that topic, since the same idea recently came to my mind. Would be another point to work on, actually had to be done a while ago already. Yea, I know, it's on the feature list, but when was the last time something actually got implemented from there?
So,
I'm pretty sure everyone of you wanted to add a name, but it got blocked by some account, which was having no former clans and never been seen in the game at all. There are tons of players with only one single name on their accounts, making them not available anymore. This also will bother new players when they want to create their account, but couldn't use the name they'd like to have. Sure, first come first serve, but does this still count for those, who joined the server last time like 10 years ago? With no former clans and no other names on their account? I don't think so.
Same thing with clans. There are so many clans with only one former member, also created 10+ years ago and (probably) never used. Blocking both names and tags.
Plus delete the non-activated accounts. (Guess that's obvious)
Also, if all of these would be cleared up, people wouldn't have to bother jitspoe with questions about giving them names or clan tags anymore. And as stated above (more than 6 years ago), jitspoe doesn't even need to work on this for himself, he could choose a few people to do so. I'm pretty sure there are couple of ways to solve this.
