Lately I've been getting the warning, "letting time run out may result in a temporary ban" several times when I was thinking about a move for a while before concluding there was no way to save the position, and resigning. I don't ever recall getting this before. Was there a change to the calculation of how long you're allowed to think before that message pops up? (And how long, exactly, are you allowed to think in a 2|1 before getting the message?)
