Forced name change resulted in Trade site issue - can not use it

Hi guys,

Due a strange course of events, I got my nickname forcedly changed after receiving some weird message while playing yesterday and can not use the trade website ever sice.

I think somebody I traded with found 'PredatoryProfessions' as offensive nickname, so I ended in this situation. Frankly, I find nothing offensive in the nickname as it was part of the shadow character description when selecting the character, but anyways... Guess is gone now, but would still appreciate if you could restore that too, as it simply makes no sense. The whole game is about killing stuff, surely cant be that much out of context.

Could you please recomment a solution?

Thank you in advance,
Volen

fixed it , apparently steam got unlinked following to the nickname change.
Lmk if I can have my nickname back! :D
