That's one possible factor but even then usually the truth came to light easy enough that nobody really cared in the end.
@Negan : ***man nobody tells me anything and even if I did know about it, I'm not gonna risk my account for a quick payday. Salvage bans should have made it crystal clear that the devs don't *** around.
If anything they're probably going to have to go thru a load of logs again to see who did what like before and then the hammer is gonna drop hard.
The people who bought medals I don't see getting banned however the players who used this exploit can probably kiss their accounts goodbye.
