he can use hampa texture but he cant sell them

Yep. Hampa has openly said that anyone can wear his set, just can't resell it.

I'll confirm that hampa allows people to use his textures so long as they don't try to sell them, although he prefers that people make their own.

So yeah, no rules being broken here.
