Way to completely blow it out of proportion. If someone really doesn't want anyone talking to them or to play with minimal interaction, there's already an option for the rather extreme you're suggesting: turning off your damn chat. People that want to be antisocial will be that way no matter what you do or say. That's completely different from people who don't wish to hear from RMT spammers that never usually interact with low level players anyway.
I have plenty of friends, I join public party finders often, and I'd say I talk to a fair bit of people every day in this game. But I can honestly say I haven't spoken to one level 15 person over the past few months outside of Duty Finder where most of the people aren't even on my server. That option barely hurts anyone.
