I don't know the ins and outs of this internet stuff, I have no idea what a "chan greentexts" are but I could easily believe the story In.The.AM told simply because I know several teachers and former teachers who have had similar types of "discussions" with students that have ended up with the teachers being cussed out and even threatened with physical violence.
It is amazing how many parents now a days even let their kids disrespect themselves. I spend a lot of time in hotels and restaurants because I travel for work and I see plenty of it in those places.
