Why Indonesian are so toxic ?

Not true, can't select Russian flag.

Sorry for the late comment, I'm indonesian, well as most of you probably already know, indonesians are known to be friendly, but that's irl, most indonesians on internet are the exact opposite. They can be very toxic, and in games (mostly war games like, mobile legends and free fire (the most popular game on indonesia)) there are lots of trolls, about these trolls idk why they do that, they probably just see games as "games" and didn't take it seriously so they just trolling it, honestly it really annoying. Hope my comment answers your question :)
I bumped into your post by googling the exact same thing. I was also wondering why it is always the indonesians that are that toxic. They always struggle to beat me, but the second they have an advantage start writing stuff like "noob" "looser", etc. I'm mot really mad, but it's definitely frustrating to know that they go through life with that attitude. Really disgusting people.

Sorry as an Indonesian.... they supposed to be friendly at all.... BUT SOO DIFFERENT IN INTERNET. They not gonna think it's will make a bad looking attitude for our country :(
Probably because with a high number of population, the rotten apple will become more noticeable. Usually, I get toxic players from india, but there's also really nice people coming from there, so at the end of the day, it's just statistic and a lot of assumptions.
well, this is my uh, 7th account, the 6th is the one that post this, yeah, they still toxic as chernobyl roof after the explosion, switched to lichess, came back and the first cheater I met was a indonesian,the reasons i know he is cheating, 12 seconds on every move, i proof it by blunder a knight and he take uh, dozen of seconds to take it in a compelete lost position for white as well as a long stall between move from very fast to very consistant. also, switched to lichess if you want less toxicity and to study chess better.
god damn it, they still play in a nasty way, from 800 to 1700, yeah my lichess positional knowlegde does nothing when compared to all the trick indonesian chess player use to be honest, damn, 1 mistake and i gone, either i met a ton of stockfish user or like 1400 here are just like 1200 in position and GM at tactic lol
It not just a single time or two that I saw a toxic Indonesian, but most of the time, spanning from around 800 ratings to 1600+ for me, from trolling playstyle to straight up just trolling and cursing their opponent, like my recent game, a few match or two before I'm doing this post, well, I'm messed up for mouse slip the opening (suppose to be pirc but it something else) and gone into a horrible position, and fell into a near mate situation which is the first time he messed with me and a bunch more, that pisses me off as at the end, he harassing me, then accept the rematch, just to abort right after, and still online after that, just not playing showing that he is want to make other mad, and that the final straw. Is not the first time that I encounter this type of player, and most of them are indonesian for some reason, from all my account (6 in total) spanding from low rating to around 1600. Please, I'm really mad right now and if you can explain this, thank you and I hope I can crush every Indonesian chess player that i meet until the are no longer toxic
