I made a summary for Out of the Loop people:

Cjayride is an American guy streaming in Taiwan. He is generally regarded as a wholesome streamer by his audience and this sub, with some of the least edgy outside-IRL content on the site.
The first witch hunt started when an edited video of his steam surfaced on some gossip news site, showing him littering. It was footage of him leaving a cup at a metro station and throwing a fishball in a bush. Found a video, probably not the original here
Clips of him being ''disrespectful'' edited into a video was also shared. [video needed, please share].
He got stream sniped by Next TV, who I believe were the original instigators by sharing and writing about the littering video but I could be wrong. Video here. Cjay refused to answer and claimed he had trouble understanding the lady.
A couple thousand people harassed him on social media in this period. His Twitch, YouTube channel, Facebook and Discord received a flurry of angry netizens.
He apologised for littering on camera. Twitch proposed he does community service.
He spent at least one stream after this picking up trash off the street. Since his channel is gone for now, I can't link any clips or vods. [I don't know if he actually did the 100 hours of community service proposed by Twitch].
He also got a 20k$ fine for flying a drone into restricted airspace. He claimed to be unaware of the illegality of his actions. He was reported by people still angry over the littering incident. I believe he is still working on fighting this fine. [Any more information about the fine is welcome]
About half a year later, just recently, he went to a hotel with a sauna and hot tub with a bunch of friends. Two girls, one Taiwanese, one HongKongnese, as well as streamer Jakenbake and Dustin. While they were in the hot tub, the chat spammed ''EZ''. Taiwanese viewers interpreted this as ''Taiwanese girls are easy'', not knowing EZ is an emote of Pepe the Frog in a trenchcoat with sunglasses on. Everyone with the BTTV Chrome extension installed can see it when people type ''EZ'' in the chat. It basically means ''cool''.
They also had an issue with the title of a clip someone who is not Cjay made.
This new witch-hunt was fuelled by a popular Taiwanese Twitch streamer ''ckkos44444''. He and his viewers doxxed and threatened Cjay.
There is a (~14k) Facebook page about tracking his movements through Taiwan.
Cjay is banned on Twitch for a few days with little explanation, and shortly thereafter, banned again.
The Taiwanese streamer quits Twitch for a few days. It is merely speculation at this point that he renegotiated his contract and used his influence to get Cjay perma-banned.
Now we've arrived at this video and Cjay probably feeling forced to flee Taiwan.
Some trolls have taken the opportunity to go about calling Taiwanese girls EZ and spamming ''China #1'' memes in ckkos44444's channels. I can imagine this is not helping.
EDIT: apparently I was too ''biased'' according to someone in the comments, so I've edited out most personal comments. This may also make it a more pleasant read in case any Taiwanese come across this thread. I have also added videos, added more info and made other edits. If the facts aren't correct, please correct me, I'm working off memory and other comments in the thread here. It's also more difficult to get a grasp on things with regards to the gossip articles and the actions of the hate mob since we're dealing with a language barrier.

I'm not going to call it anything else than a witch-hunt and a hate mob, we're talking about doxxing and threats over a few instances of littering, flying a drone in a park and a misunderstood emote here... on top of some out-of-context ''insulting Taiwan'' nonsense. I care about this because it seems so obviously overblown and a lot of misinformation is being shared. And context matters. It always matters. You can't just take a few clips of a stream, edit them around and character assassinate someone over it. There, that's my ''bias''. I don't like hate mobs. I also don't get riled up by fake news media into harassing people.

Please reply with any further information or corrections to this ''mother'' comment.

EDIT 2: I see a lot of people from this sphere of Twitch going into Taiwanese spheres and trolling with ''Taiwanese girls are EZ'' and ''China #1'' and all that. None of that helps Cjay's situation nor is it proving the hate mob wrong. I also made other minor edits.
