Could this be true???

A guy flying Korean Air said that he saw BLDSWTTRS playing in Korea last year. He said that

1) bldswttrs is an ivy league professor who visits Seoul every spring
2) he advertises by losing huge in small casino games to get invited to private cash games
3) that he is the sickest hand reader alive

When asked how he knew it was him, he gave a vague "I am not at liberty to explain that" answer. So this could be total BS and I ignored it for months. But, recently: I was talking to my buddy who plays in Seoul and he did say that there was a caucasian professor who visited from time to time, nicknamed "the vacuum", who DESTROYED the game for several days last May, calling with Jack hi and being right, etc.

Do we already know who BLD is (I dont) or is this possibly a legit sighting of him???
