Welp, dude blocked me, even though I tried to explain factually and politely that I wasn't asking for advice, and don't take unsolicited advice from strangers.
Guys do be fragile, I guess. Sometimes I wonder why I bother explaining myself instead of just muting/blocking/ignoring, but some days I guess I just get fed up with it and want to (gently) push back. I tried. Maybe they won't bug someone else in the future!
