More clan restrictions

Its seriously about time we get more clan restrictions, yea it's been said before but I thought I'd bring it up again. Im sick of level 26s requesting to join. Even if you put it in all caps in the description: LEVEL 65+.
I know no one reads Ideas and Feature requests but whoever does: Please give feedback and add more suggestions.
Key: ! = Highly Suggested : ? = Just a thought


Level limit!
Town hall limit?
Certain troop level limit?
Gold grab achievement limit?
Release the Beasts achievement limit? (Simply if the leader puts it to level 2, you only need to be able to train archers to join, If its level 3, you need to be able to train dragons.)

I like the sound of more clan restrictions... It will help to keep low levels from getting in, or requesting and invite.It Would be good for high level clans if you could put a restriction saying that you have to have completed the friend in need achievement to join.
