Mysterious disappearance of a player

What happened to player #2805, David Wilkinson (U.K.)? His name disappeared from list of players in Go 19, Go 13, Go 9 and Golem's ... Actually, he has not been playing for more than 32 days and it seems he keeps on getting 24 hours more everyday in all his current games. Has anybody got news from him ? How can one explain this mysterious fall into a black hole ? Thanks for every clue :-)
