As the title says - just like war invites - make a toggable setting if you either want or don't want to receive clan invites.
Reason for this: yesterday i kicked zenga with an alt from fuma to test if an officer could kick another officer (yes btw). Zenga clanless, reinvited but got the '3 max inv per month warning'. Meaning I have to stay clanless till end of september. No big deal i can live with it. Thought it came cause i merced too much, but i just realized it didn't do that with zenga (only 1 time).
What happened was that i get random invites from noobs to join their clan. I clicked by accident accept/yes 2 times. I remember 1 time thorin with armed and 2nd time i forgot. I know be careful on what you click, but it's pretty easy to lose your attention

Anyways, a simple setting could prevent this in the future.
Note: having to join/make a 2nd clan does not sound like the proper solution for this.
