Why not PM the one person you want to have your username rather than share it publicly and get mad at friend requests? Honestly, you don't sound like a very cool friend to have.
Also seems like a good way to for sure get your profile name added to a ton of spam lists.
Eh, I replied in the thread too in public instead of PM. Thought came to my mind but I figured no one would mind.
P.S. - We both got sorted.
