Hey, no problem!

The fb page has multiple admins, who all post differently.
I always credit artists and try to inform them that I posted their artwork, not every admin does it the same way.
I try to get them to at least credit artists at all times but because I am not the main founder of the page I sometimes miss it when things aren't credited.

I'm trully sorry when people's work gets miss-credited or not credited at all! I'll keep having my eye out for it
