They stopped multiple offers coming in on one move. However, there is no way to stop your opponent from offering a new draw offer after every move is completed.
If you believe the behavior was unsportsman like, you can report it using the report button on the player's profile.
I get completely distracted from repeated draw offers.
OK also I should stop 10+0 in which you sometimes play moves too fast without looking..
but seriously I don't like when people cry sportsmanship but repeated draw offers in a losing position to prepare dirt / cheese / whatever you wanna call it... It's bad sportsmanship, sorry.
there's a reason in lichess you can only offer a draw once. I mean it's just disrespectful to deliberately annoy your opponent hoping for a blunder in such a lost position. Probably some kid but I was actually in rage after this game
