Why am I being paired with players I have blocked?


Are you leaving live after blocking and getting back in after? I don't know when the block list loads, but it may not check immediately.
But you shouldn't be paired with them in auto-seeks:

You'd have to submit a ticket. It shouldn't happen in auto seeks. (You could get paired with them in tournaments though)

I am auto seeking on the chess.com app and it has happened multiple times.
If you mean the app on Android or iOS, it's also possible that it will take a brand new session in order for the block to work correctly.

I block people who stall / abandon games when they are losing. And yes, twice in the last two months I went to block one of these guys and was told that I had already blocked them. I don't want to play with the miserable losers who don't have the courtesy to resign lost positions and instead get some kind of sadist joy out of making others waste time.
