I don't think they're trying to stop people from uploading, they're probably pissed because the previously uploader censored out the sex scenes.
lol it's not uploader fault. blame tappytoon for censored the sex scenes cuz this is official translation from tappytoon https://www.tappytoon.com/series/tieduptwins/1
Flipping off the uploaders of previous chapters and signing with “anonymouscunt” is pretty obvious snobby attitude and what the other person said, the uploads here are from tappytoon who censors scenes whereas the Lezhin raws do not. So they are pissed that someone uploaded chapters (for what reason only they know)
Chap 15 uploader was trying to stop people from updating but I’ve seen the other chapters start popping up on Imgur from different uploaders I follow since 15 was released so evidently it’s having the opposite effect Bless you all uploaders! I’m broke af and y’all make it possible for us to read these so thank you!
