This!
I admit to watching a slew of reaction videos randomly all at once every few months but damn they are fake 99% of the time.
Also causal racism/sexism/REALLY creepy as shit people do and no one calling them out. Particularly living in Japan and having to see these "how to pick up Japanese girls" "Do Japanese girl like foreigners" "dating a Jap girl" and so on -shudder- these videos are goddamn plague but every foreigner/group based in Japan with a youtube account seems not be able to help them self but make these videos and they are all creepy as fuck. Even worse is if one pops up on the play list youtube keeps fucking recommending them. -watches video of a dudes opinion about an incident in Japan, next video ques up on auto play because its his most watched, video is 10 minutes of him going up to random girls and school girls in the street asking them plainly if they like black men-
common with this shit.
Also asking to like and sub before the video plays.
ALSO ALSO having some long ass dubstep backed intro. 5-10 second only people. Or just have the title of your channel. Or a quick line or two about what the topic will be. Kind knowing you can click a 8 minute video, instantly hit that 1 minute 35 mark and THEN the actual content starts is insane to me.
