For me it was a worry that by some really odd chance, although is minimal, it's not impossible that someone from my real life could recognize me. At the beginning, I had no idea how far this website would reach and what demographic would it attract. I wanted to start here completely anonymously but that has really very limited options so I made this account to be more myself, more recognizable but also playing it safer.
I only use the first account to see some blocked comments in threads now.
