If a noob's not going to respond, I cut them some slack. No point in banning them for being "incapable of socializing".
if I continue to talk to them and they still don't respond I will tell them how to type a message. historically however this does absolutely no good and they continue to be silent
so that means there's one player pointlessly taking up the limited space available on my server
and generally
I wouldn't get rid of them immediately but if the amount of players climbs towards the limit then I will ban them
I would, however, ban someone capable of talking who specifically ignored my hello, because that is undeniably rude and I don't want that person on my server
