This is most certainly boombl4.

Here's the PM he sent me:



As you can see, he clearly states "if you think i am someone else than me, then place negative feedback."

And I do think he is someone else, so I left him a negative feedback, as he requested.

Turns out he didn't like that.

After calling me a "Pedophile and scammer" 5 times in my trust feedback, there's no way I will ever remove my negative on his account. However, I might update it to reflect these recent developments.
