Bottleneck is correct!
I got a limit of 30 member slots, and the reality is any serious active player is going to have 2-4 accounts. Then we trying to make room for a new set of recruits which takes weeks to flush out if they are even active or responding enough to keep. Like "Oh wait let's create a second level 3 clan, give it the same clan tag". Put our low levels in it, and keep high levels in the main one. Then we come to find out there is no way at all to get to clan level 3 anymore, so if we go with that idea. They lose out on all the bonuses they could get with clan level 3 or higher.
Clan exp to level the clan and get great bonuses, I am game. We just need some reform to make it POSSIBLE to actually level a clan in any good time frame. Got a problem with people with multiple accounts grinding 24/7 and get clan level 10, deal with that problem don't punish everyone else for it.
