that there is suspicious activity on my games' pages
That would mean, your games are not delisted as such. They are quarantined. Delisting is a side effect. Using a vpn a lot might trigger that. Basically the automatic always thinks your account is hacked and they cannot affort to "protect" accounts against this detection, becaue there really are a lot of hacked accounts. That would be my guess about your situation.
I am now wondering whether it is something in the Ren'Py generated APK files. I had one player tell me that their virus scanner reported problems with it, and a search on the internet showed me that some virus scanners do that, but it is a false positive. However, if itch has a system that triggers in the same way, it would explain why any change causes them to quarantaine my games (and other people's games as well). If that is the case, then perhaps using a different Ren'Py version would resolve the issue (I am currently on 8.3.7). I would try this, but the problem is that I am putting my games in quarantaine again if it is something different. If only itch would tell me what the issue is...
