Coliseum got me banned

You did something you should not.  You beat a tier with “toons that are not cleared to get that far”. You broke their gate.  

Lucifer's Daddy hasn't been used for appeals for a while now, follow this link.

Lots of people have been banned because CG didn't calibrate their auto-ban with their newest OP character.

Cheers. I filled out that form twice so far and nada.

Yep i got banned also for being too good at thier BS 

10 yers playing i guess i havnt spent enough! lol

I've only spent about $300 so not enough to be important.

i will never spend again

you broke their excel sheet.   Coliseum is throttled by excel stats.  this is why all of a sudden you start seeing the -1 damage.  coliseum is actually the worst thing to hit this game 

Just happened to me yesterday I beat the tier 7, did you ever get your account back?

I filled out the appeal form twice and it took them about 5 days to unban me. That's the only thing I could find out to do.
