I think you might be wrong about it not being an ELO problem. At low ELO I am not noticing too many problems. And they are easy enough to ignore (game isn't lost if you block one player).

Anyway, most of the internet is filled with the kind of behavious you describe, so good luck in the offline world, I guess.
