The limits in Quality were really worth the last time, when just was allowed to have 5* as max, then the transfer windows are easy controlled because transfers appear in the messages, + players should post a pic with the tokens wasted in the transfer, and despite that some player can buy tokens and waste 20T for a player and declare 1T.... the price is increased with every token, so I will say, that the Q. limits really do a lot to do it fair and equal, thats why we had a season with 5 teams with options for the title in the last week...
About referral Tokens, as I did last time, I post screenshots when season start, during and when finished.
And that, about the OMA league, people know the rules, and the confidance is a base to play these type of leagues, + the own responsibility, we all know the rules and of course, that if one wanna cheat "always" there's a way, like in T11 there's a way to convert every competition in a sweet cookie easy to eat.
About old cheates, existed? yeah, and were hunted. LOL....
