I think it's because it's live chess, you can choose who you play, but not who plays you. It's like OBT play. Thats not written in stone, but that is what I think the reason is.
Resolved; Live Chess - Block List ?
Sort:
Can you just click on someone's name and choose "Block Member"?
why???
feyfey: Unfortunately there are many ways to be an a*hole without crossing the line into breaking rules. Just the latest example: my opponent plays some 30 moves of an opposite Bishop ending with completely symmetrical pawns.
knightspawn: I don't see how that's different with turn chess, and the feature is there for turn chess.

[COMMENT DELETED]
Why is there no "blocked" list in Live as there is in turn chess? There are many players who I don't ever want to play again.
