Ironically, when you scroll down here (for example):

According to his own biography he (Nam Nguyen or Nam Nguyen Hai?) got a PHD in 2011 from the Sorbonne in Paris (didn't know they hand out PHDs in bullshytting and copy/pasting, lol), and sooooo after getting his PHD he started to coach tt (full time?/part time?) at a small french club in or around Paris...
Pretty much everything he had ever said and written smells as fishy as the pantys of Beth Ditto.
We do have TTD members from France, likely from the Paris neighborhood, too, so it should be possible to track him down. Question is, do we want that, and if we do, what do we do about it? It's not like we can arrest him and/or confiscate his IT equipment.
