Just a bit curious, before I state my answer paid services are against Bungies TOS and as is cheating obviously.
I believe that Bungie should take a similar approach to how Valve dealt with CSGO gambling, ban accounts and start filing cease and desist orders against the website owners
As for Cheating, bungie should implement IP bans with [b]DEFINITIVE[/b] proof and issue normal account bans for suspected cheating, if innocent remove account ban. If not then go from an account ban to an IP ban
This is mainly about cheating, but cheating and paid services do go hand in hand a lot
