The crux of the issue is if the behavior of these students harms the learning environment in any other way. For example, raising their hand to answer a question every opportunity they get meaning fewer of the typical students get to answer and learn from [their] mistakes, or running these private tutoring sessions then giving up if no attractive women show up / giving the women they're interested in way more attention. It also isn't a good look if they're bad at teaching and use the tutoring session to just do peoples' homework for them.
