WHY is there no bigger punishment for leaving the time than aborting the game?!??

Tell me how it's fair to make the opponent wait for 5 minutes than for 10-20 sec.....? Lifelfess ridicolous noobs still letting the time to run out why cant you IP ban them after 10 times? I play many games but none of them has this annoying thing like this. In any game my opponent won't be as rude to me as there yet its just a chess site.

Not only is it rude to sit "after 10 times", it's a Terms of Service violation and players are banned for it (and the site automatically issues warnings about sitting):
lichess.org/terms-of-service

But afaik letting your time run out for 30 minutes in a classical game isn't considered any WORSE than aborting one game (or sitting for 30 seconds in blitz), even though you waste about 60 times as much of your opponent's time.

There is greater/swifter punishment for somebody wasting 5 minutes vs. somebody wasting 10-20 seconds.

Forget "IP ban". IP's are not bound to persons.

In my days, we would stone to death the unfaithful women, burn the witches and brick the loose nuns.

We need bigger punishments. While we are it, let's revoke the habeas corpus.

could you post the names and home addresses of players that sit for more than 5 minutes to lichess.org/hallofshame ?

I get that you are joking. But doxxing players no matter the reason is not the way to go. Assholes should be allowed to live in peace just like everyone else.

There are sometimes reasons/emergencies, like disconnections of internet, or falling asleep. Although in a 30 minute game this is wasting more time, actually if people do this repeatedly in 5 minute games, then the time adds up to the same. Also, in a 30 minute game an opponent can also abandon the game for 10-20 minutes without worrying they would run out of time themselves, so it's actually less stressful than when people disconnect and let themselves flag in shorter games. If people are doing this repeatedly regardless of time control, that's when they do deserve the appropriate response from lichess.

Turn on the notifications, play another game meanwhile, a shorter one.
