Device ID doesn’t even need root/jailbreak to change. Just a factory reset.
WIFI MAC is easy to spoof. Cell radio MAC is possible, but much more involved, and you do risk breaking things that matter (but if you are at this level of cheating, you are probably not using a device you really care about that much).
Every protection has a possible circumvention–but, some of these are pretty easy to implement, and would reduce the near immediate return of some. Especially the cell radio MAC blacklist. I expect any cheater who can do this is likely not getting caught up in ban waves (or, not usually).
But… that’s just speculation on my part.
