Cheating in Fog of War Variant - An Investigation

As for cheating, the only time I have encountered a cheater/ even suspected a person of cheating was at the founding of the variants cc. When fog of war was introduced, there was this player named Baobab123. He seemed to be extremely good, even undefeatable, back then, even compared to strong players I played back then like Illingworth and A1t19 (He went against Illingworth and lost like once out of 10 games). His highest FoW rating was 2800, and he used this weird opening that wouldn't seem to be good at all. Then one day he completely stopped playing fog and only played horde. Pretty sure he was abusing an inspect element ability to reduce the darkness of the fog, and I'm assuming that whatever this exploit was was patched that day. Since then I have not seen anything suspicious at all. None of the top players I've played seem to be cheating.

also, to see Baobab123's rating, just search for his username in the archives, it'll show up. 

Also, it seems like his rating has been reset or something, but you can still look at some of his games for the rating.
