On Pokerstars- is there a way to check another player's stats and how much they have lost online?

Question

is this even possible?

Answer 1

Not on the sight itself, and I haven't found one for cash games, but you can go to sharkscope.com for SnG results and officialpokerrankings.com for MTTs

Answer 2

Sharkscope is great to track sitngo wins, however Pokerstars has Explicitly banned its use, so be careful and don't let anyone know you are using it (ie. don't tell someone how bad their stats are in the chat window)
