I looked at their profile. Yeah?
I'm not fond of reporting people as cheaters, by name, even with an explanation, given they aren't here to defend themselves. Even worse when you haven't stated what the problem even is. Problems should be reported privately. If you didn't give any better explanation than "look at their profile," I wouldn't go to the trouble of trying to figure it out.
Some people are a bit quick on the draw to skip turns of others. But they were also skipped by others. Not to mention that when you're a high level player, skipping someone else is a dumb idea cause you have to share a tie with everyone. I don't see obvious win trading. (With two good players it's logical they would sort of "trade off" wins.) They joined at the same time, but perhaps they came here to play a specific game together. And yes, they both have a high number of red thumbs, but we don't know what that is from. Maybe they are rude. (And anyone can note their level of red thumbs without a post.)
Point is, I don't see anything obvious jumping out at me that proves cheating, not just looking at a profile. So not a good idea to make accusations in public when you don't even say what exactly the problem is, other than "they play together." Oh, that's a disaster. We can't have people playing together.
Not saying they aren't cheating somehow, but I just don't see anything obvious from their profiles. If there's something you know, you need to state what it is. (I don't know that game, but if there's something obvious going on there, you still need to state what it is.)
