Yeah, it happened but now fans have evolved they only fight each other via social media in the name of hate comments.

At least there is no property to trash now since things are happening digitally but spreading hatred still happens, that is an attempt to convince others to hate them as well.
And it's not just in loss even after win there can be serious issue like the one happened in IPL 2025. RCB won the title and went back to their home stadium for people to celebrate because this is their first championship since the beginning of IPL but it costed 12 or 18 lives due to the stampede that happened at the gathering.
Yeah, now they are getting banned, limited, and issued strikes to violating community guidelines and other rules. I can see there are meme wars between the fans of Asian countries. Afghanistan, Nepal, India, Pakistan, and Bangladeshi fans are mostly doing this. Also, Sri Lankan fans do not leave anyone. They do the same thing. There are a lot of troll pages as well that just post sports memes, mostly about cricket.
Some people might criticize them, but some others find this funny. Those pages troll the players and the teams when they perform poorly. So, I think this is both criticism and entertainment. I think you have heard about Lords pages.
