Is AUTHOR wrong in the post ? POST : Throwaway account for obvious reasons. Also, I’m on mobile so sorry if there’s any formatting issues.

I (15M) am a part of an online friend group and have been for around two or three years, with a few of my buddies that live around me, and others that are scattered across the country. The online people had met with us over Xbox and it pretty much went on from there. G (14F) is a generally timid person, but has been made very uncomfortable by Q (19M) on numerous occasions. J (19M) lives near Q and they are very good friends.

Q was always a sketchy guy. The fact that he talks to us at all is strange considering his age, but that is the least of his issues. Q was always especially affectionate and kind whenever G was around, and it was just creepy, but we had not realized it before when we were younger. When G was 12 years old and Q was 17, Q had even asked her if “she trusted him with her nudes” and had mentioned that he “trusted her with his”. G was very uncomfortable and had obviously answered no. She only informed me and one other of my buddies of this a few months ago, and we have been much colder with Q since then.

Q has also talked to us a lot about his adult issues and even his sex life, and even if we told him to stop, he would simply talk about it another day. He is simply not welcome with us anymore. However, J is a different guy. He is far kinder, and cares about pretty much everyone in our group equally. It is still a little strange because he is an adult too, but he isn’t a predator, I hope. He is very, very depressed and struggles with it every day. We fear that if we were to kick Q out of all of our lives, it would hurt him. Q is pretty much his only real friend. 

WIBTA if I, and everyone else in that group, blocked Q from every aspect of our lives, possibly hurting J too?
