Toonslab seems to work fine for me. Whenever I get banned, I am able to appeal it within a few hours by sending a ticket to Toonslab. I had a 3,000 hour long ban and I was able to unbanned within two hours.

Basically what you should do is be as nice as possible. Do not even mention if you're angry or pissed off. If you do that they're ignore you/reject your appeal. You just have to say "I didn't do anything" and "please unban me, I didn't do anything."

I see so many people complaining about Toonslab being "inefficient", and when I ask to see what they typed in their ticket they literally have a bunch of curse words and they're saying all this bad stuff and threatening Toonslab to unban them. Yeah, like that's going to work.
