I'm happy to give the benefit of the doubt to people, connections accidentally dropping in a game definitely happens. My commute to/from work goes through a phone signal black spot and I used to forget, and start games before the bus went through it, then kick myself as I watched myself time out. But that'd be mid-game or even when I was up. We all know the situation I mean - an opponent's connection has been perfect all game but they disappear instead of resigning the moment it's clear they're properly losing. C'mon, you *know*. Ice Cream Cake makes a good point.

Trolling is not a "contribution". If you are trolling, at least try to be funny.

I get people abandoning games pretty often and if it happens 'accidently' right after their losing move I always report. I dont expect from them to say GG every time but at least they can resign to save some dignity. For some reason I always imagine abandoners throwing their phones to the wall, mentioning my mother and then cry

I see their mother taking their laptop away and telling them to clean their room. Some abandon for no reason.
I think abandoning a game is an act of petulance. On longer time controls, resign in good grace if you are clearly losing. On blitz and bullet games, play on! So, you blundered. Your opponent may blunder back. You may win on time. Quitting is childish.

it happens all day everyday
for some people its too hard to admit that they failed and they choose to run away and live with eyes closed..
weak minds
Abandoning a chess game is the equivalent of a boxer climbing out of the ring mid-fight and walking away. Pure cowardice.
I've occasionally "abandoned" games after my Internet feed was temporarily lost.
I had someone abandon a game yesterday - there were no indications he had Internet trouble, but he was in check and the game review stated afterwards he was six moves from being checkmated. He let the clock run down for ten minutes before I won on time. I didn't bother reporting him - I spent the time working out how to nail him down if he did resume the game.
if that happened they would have no players below 500 playing and they need those players to keep site going i agaree i hate when it happens but there is little you can do and they have thought this out a lot it just makes sense to let it go and accept there are many people here who !@#$%^&*uck uped

Abandoning games is against the rules. However, even though I agree it's annoying I personally would never report someone for this because I think it's minor.

Sometimes a player might be in a game using his phone, and they get a call which interrupts the game. Sometimes they can get back to the game and sometimes not. In the former, it may look like stalling, and in the latter it may look like abandoning the game. Perhaps the best way to deal with it is to go through the log of games after a few minutes and reach out to the player first. If something happened where they could not resign, they should be willing to say what it was, and maybe do a rematch. That might be the best thing before just reporting someone.
Suggestion: I think it's okay to report, especially if you see that they have a good internet connection. I may give the benefit of the doubt if they have a poor connection.
Yes, unintentional abandonments happen, and sometimes for unfortunate reasons. Of course you, as the person on the other side, can't tell what happened. But statistically, if the person is an unintentional abandoner, they probably get only a few reports and no action will be taken.
