There are a few people that come to mind, but I've never been one to call anyone out, because you really can never know who is, and isn't breaking TOS. But I'm sure we all have our own suspicions. I'm sure some type of punishment could be given out to players who continue to group with reroll cheaters could be created, but it would be hard to enforce, and as lame as it is, I cant see it justifying a permanent ban.
TLDR, yeah it would be nice, but its prolly not gonna happen.
