Anytime you post anything to the public, you have to expect this sort of thing, which is why I could care less if anyone kitbashes, alters, or does whatever with my models.
If it earns you false credibility by you claiming you built my mesh, oh well. I hope it works out for you. If you get a job because of them, I'll be glad to be a reference ...

Just remember, the truth has a nasty habit of getting out there, too.
It's a shame.
I rather liked your models - especially the Predator and the Avenger you built from designs at the Starfleet Museum.
Anyways, good luck and keep building, whether you release them or not.
I, Mudd.
