I am friends with a college girl who wrote me this on discord:

I find our interactions interesting, and don’t feel pressured want to do anything for me. The only thing I would want is for you to just try to not talk to underage girls, because I’ve personally been on their side once, and it really has long-lasting effects that you may never even realize

I'm in college right now and I have lots of discord friends including a couple girls that might be underage. Should I heed my friend's quoted advice and just block the girls until they turn 18?

Both friendships are completely platonic and 100% above-board.
