@salsa321 has a lot of designs and interaction in this forum so it is easy to prove whether his account was hacked.
He is a designer (Graphic Design Service & Writing | writing WP,ann thread,bbcode,and more) and he has some communication with a lot of people so they can be asked to check the authenticity of the hack. (archive)

@condoras gave him 2 Merit, So he might have contact with him.
Looking at the trust list, he has reached out to @Bit-Exo.com, so we may get more information.

According to my personal assessment, I think the account has been hacked.
