It's surprising
BetFair don't pick up on it as they seem quite tight on this. As you know, Runadrum and I cannot play at the same table (one of us forced to sit out) even though we are on different PCs, but it presumably recognises we share the wireless connection. If he is multi-playing he at least cannot play 2 at once on same table.
I did try to say this (well some of it!) in middle of the game but every time I tried he was all-in and you can't chat!!
