It’s very obvious that there are still cheaters in the system - I see new ones everyday. As we move to a new system to get covers, I’d like to know how many (percentage-wise) of the existing exploiters have been handled and how D3 plans to prevent it in the future?
Before making vague accusations like that - are you reporting them?
The Devs made it very clear that the exploit is obvious to them and is managed on a per use basis (Sandboxing).
You accuse people cheating, yet have no idea how they got their covers. Did you see them cheating? Do you know them and have first hand knowledge? I didn’t think so.
Are you sure people aren’t opening the tokens they have been hoarding for a month+ in anticipation of this feature and having their rosters make massive leaps forward? I know a lot of people like that.
Depends. How much money have they spent?

The OP is likely referring to all of the top players with multiple 5s. I’ve seen players with 3 SS’s, 2 OML and 2 Phoenix.. that is insane! That is a lot of 5’s from token hording/spending money. There is a player in my SHIELD Simulator with 7000 pts.. yes 7000. that’s crazy. How would you not think those players are cheating? So I do not blame the OP for thinking that but there’s nothing you can do but report them and those players might just be legit (and lucky!)
Joining many buyers clubs is not cheating and buying legendaries with the resutling CP is not cheating. Spending 1575 HP a day in the sim to get into the 7k club is not cheating. These are all interrelated. It’s what people are doing to stay at the top in their season brackets in PvP or have some kind of trophy.
Hit a sore spot, did I? When I see rosters with more 5* covers than 4*s, I can guarantee they’re cheaters; and yes, I report them but that doesn’t stop me from seeing new ones every week. In fact there’re 2 active ones at the moment but it’s against forum rules to post their names.
There are two above 7k in my Sim bracket. One is a notable name from the forums.
The notable 7x450 player has also been discussed ad nauseum.
7K? Pff.
Top in mine is 8500 and 8000.
A lot of money to some is nothing to others. Most people cant step out of their narrow frame of reference.
Might be the same bracket. I haven’t opened sim in a few days.
I see obvious cheaters pretty frequently. Some got more 5* covers than 4* 
I report them and usually it take them a long time (2+ weeks) to remove those account. Come to a point, I stop caring, I’m not a MPQ police, nor it is my job to do so.
