You could check out this topic
which shows a bunch of clans. I would not recommend this as most clans don't exist anymore or are inactive.
If you are willing to join EarthFamily you can contact [GS]Lightz/the_mask500.
We are highly active, have 48 active members (out of my head), an official YouTube Channel
We are still growing and are currently working on a website.
Our requirements are:
Rules are the same since Yuuki and I made this clan which are:
•Loyal & Preferably active.

•Able to speak english (doesn't have to be perfect)
•1.70kdr/30%HS+ & legit with no hacks.
Feel free to contact me ingame if you have questions (or here if you like), my IGN is Absolution (absoiution).
