can you get banerino for loud or high pitch kiai

I guess your kiai is fine as long as it doesn't contain offensive or racist language. Not entirely sure tho.

well ppl like Onix and Gentleman used to have very loud kias and sounds however they changed them so there could've been a rule change

General rule of thumb is: if you're afraid something like this will cause problems and get you banned, then don't do it. Annoying custom sounds suck.

If people think your sounds are fine, it's fine tho.
