The same thing happened to me. He has an auto-ban feature on low level accounts to prevent thieves / problems with refunds etc. He did mention to me that this can happen with low level players but he DID NOT mention at what level we can start having money on our account, which is also a problem for me since I'm in the same boat
I do know that you can have at least 500k on a level 26 character because that much is how much I claimed to get my son and I jetpacks. I had to do it one at a time though. Trying twice was autoban. (1m). Now I'm higher level and earning much more money per period of time (especially with all the cash shop buffs to income) so I would love to know at what level I can start playing without fear of an autoban.
