I used to be like "Oh, this is legit!" and it would also be the pinnacle where antis would be like "oh in their MR removed they aren't singing certain lyrics so Imma hate on them for lip-syncing"

Some of them seem kind of legit, others seem altered. Overall not a good source for figuring out anything.
There was a Twice performance where Sana was sick and people were sending so much hate to her and were like "there are idols that are sick and can hit the high notes" and blablabla
