I cant say I believe that it really happened.
It is indeed something of a mystery. Nobody from TBF commenting on this thread has seen it fit to validate that the 100K from KnC was made.
Or that the 100K from Phinneas Gage was not made.
Phinneas = Gleb = Bruno was pulling a prank with his original post. Check this thread, a couple of pages after that. His aim was to have people look search the blockchain for 100 k$ donations to the TBF. AFAIK, none has been found.
