- Streamers intentionally join casual multiplayer games to run around "pwning" noobs because their followers think that it constitutes skillful gameplay
- Every little glitch, bug, exploit and oversight is made public and abused to hell and back by everyone, rendering multiplayer matches a non-stop barrage of cheesy tactics and exploits
- All games are completely overrun with people spamming to promote their streaming accounts
- Streamers often intentionally "meme", that is harass other people and try to make the game as unenjoyable as possible for them
- Streamers become community figures and ultimately influence game design, despite their sole credentials being that they are "popular"
- Streaming promotes the most obnoxious type of community possible - people who thoughtlessly spam "POG", "4HEAD" and other twitch speak
In the old days you'd maybe run across one asshole abusing game design oversights to rack up kills every 10 matches or so, which was annoying but not unbearable. But now every game is overrun and infested with people playing the "meta" way and rendering the game unenjoyable for absolutely everyone. That's not to mention streamers "pwning" noobs for views. Nowadays I just instantly hit alt + f4 whenever I see someone with a name like "NoobzpwnerTTV" or "qt314YT". It's just not worth it.
