I reread D-frag, its one of my comfort reads so I read it now and again from beginning to end.
I also read The Bully In-Charge up to chapter 69, its another korean delinquent work in a world where adults dont intervene no matter how bad things get and kids are so vicious they send each other to the hospital in a daily basis. The catch here being that some higher ups at the education foundation decided to hire a 20 year old ex delinquent to go to school as a 16 year old and beat the crap out of the bullies, so he gets to dominate them. I don't think it was trying to do comedy, but it ended up being hilarious in many situations I laughed out loud, it is pretty ridiculous at times. The fights were somewhat good, but near the end it is getting into the typical delinquent manwha territory where gangs and drugs get involved in every high school conflict and also some special bullshit ability is getting introduced, which kind of ruins the "somewhat plausible fiction" element of the fights into straight-up fantasy. (similar to what happens into kuroko no basket to give some reference)
I mean, yeah somewhat, I'm just pointing out the idiocy of asking that question in a place specifically designed to talk about those places.
Also, regardless of how bad the sites as a whole are, making the transition fully is just plain too difficult, there are communities that haven't moved and no matter if you are putting effort to have them here, you won't be able to get a question about a program answered if there are 3 active people on a community
