Past violations is not a defense.. think of Music Sharing.

If you are producing a game, you may have other issues. Unless you are just using images, most content can not be redistributed.

With regards to limits on use of images or derivatives of images used to create textures, I would recommend contacting an Attorney. Telling the Judge that the users in the Forum said it was okay will not be a viable defense, should anyone come after you.

You do bring up an interesting point that Content Creators need to be aware of, when using third party product to produce content, where that third party product had limitations. It may be wise for the content creators to check their EULA to see if it reflects the limits of the content.

(Look at the old DAZ3D Product that used the model. It had a lot of different limitations, when compared to most)
