I was banned for no clear reason, but it was probably due to abusing certain resources to acquire all skills and speed up the game too quickly to pass levels, as well as repeatedly purchasing resources. After being banned after reaching level 6, I think there shouldn't be too many mods; just speed optimization and no ads would suffice. I also don't think the fact that gems don't disappear would lead to a ban because i use 300k gem for update skill and have many equipment
