One thing that boils my blood is when someone, mostly from progressive types, misrepresent and strawman another side's arguments/opinions and it's always on purpose, or attempting to act as some sort of mediator during some drama, but it's pretty obvious they don't align with the "chud" side. It's doubly annoying when they stuff their 2+ hour long video essays with so much misinfo and petty nonsense that I can't help but feel is a snide tactic to dissuade others from debunking them, since it's an exhausting amount of bullshit to sit through.
Another is when something popular or niche gets a reboot/remake/adaption/whatever, there's suddenly wave after wave of artificial hype vids getting normies and newfags caught up to speed so that they don't get FOMOd and feel left out when consooming the lastest FOTM. It even happens with internet drama and whatever's trendy atm too, where everyone and their mother makes a "I HAVE AN OPINION!" on the subject and/or milk it for views with multiple vids for however long it lasts.
Also, people milking a subject after their previous vid got millions of views. Some fag who makes those "Gaming for a Non-Gamer" vids comes to mind. It's just some "wholesome" pseudo-game dev armchair psychology video essay of his normie wife playing vidya that keep getting millions of views. They're not the least bit interesting, insightful or funny either. It's just weird hearing some dude gab about his wife in the 3rd-person.
The YT title game is also fucked with clickbait. "I never expected this" or "The developers knew you'd try this" or something vaguly titilating and it's either someone's unfunny stream highlights or outright timewasting clips. It's worse when multiple youtubers/streamers waste so much bandwidth having 3 - 4 other channels to spread their influence across the net, clogging the algo with this garbage. I could go on and on about other shit that bothers me, but I'll just list off the others that came to mind: Tier lists, channel intros, having other e-celebs read off screencapped posts, "I watched/played every show/game"
Any faggot who unironically do the open mouth soyface for their thumbnail
That and pretty much any FOTM reaction image that becomes an exploitable, especially the different renditions people make of Nu Chad. I never found the Virgin/Chad meme all that funny to begin with, but there's something about seeing Nu Chad in particular that irritates me. I think it's mainly the people who use it do so "ironically".
