Nope, no way to tell a person's gang from MP. And the other gangs don't show because either they have been banned or they have have hacked so many points that the game no longer recognizes them.. I'm not sure.

Events should be back in a couple of days though so you can start grinding for stars again. There is no way to undo an accidental purchase unless you have an old backup of your data. Gameloft support is indeed wacky. Sometimes they respond within hours, sometimes they take weeks. But either way accidental purchase is something they can do little about. The buttons are placed that way deliberately.

And hahaha 20% cheating? I think its 20% legit. Most players on Android nowadays hack atleast stars and coins if not anything more. You are always welcome to create an account on the Wiki however the report a hacker board here was closed a while ago. If you want to then you can report those cheaters straight to Gameloft. However as someone who's  dabbled with hacking plenty I can tell you that it doesn't help much. Still feel free to report them. If nothing else, it will atleast make Gameloft get off their lazy a**es for a bit ;)
