tbh, shrugging and saying "children are fighting" whenever i see online discourse has spared me so many needless internet fights for the past 15+ years
the closest i've been to online beefing was when some fucko in my local smash community (gross) made some "wholesome pr" that included bullies and harrassers, and i suggested we make a shithead pr (that i could be #1 on). and like i knew the ppl irl, so i don't even think that counts lol XD
