Is Sketchfab safe against unwanted Model downloading ?

Hi, i am planning to present some of my models that i trade on blendermarket via sketchfab.
Sketchfab offers a download option, but i want to use this option only fore some models.

My Question now is, are sketchfab models - that are not release for downloading - safe against unwanted downloading? As the files at least temporary on your device as you watch them, can they be kind of “hacked”? I don’t want to loose models that are not planned as a free giveaway.

Thank you for helping !

Well… not 100% as it uses webgl and you can infact rip webgl models(i tried at one point, but not for illegal reasons, I wanted to rip an old game model so I could have nice reference to remaster it in HD)

But I’ve also seen the ceo actively search for these forums and shut them down(Not in a scummy DMCA war but asking them to stop)/reverse engineer them

So I have faith in sketchfab

But I got a few ideas on protection
make the sketchfab version of the model, so broken(add a bunch of non manifold edges, add a bunch of inconsistent tris turn edges that shouldn’t be ngons into ngons,etc) that it’s more efficient for the theif to just buy the model than try to fix it,

just don’t break it to the extent that it makes the model look bad.

Hi fdfxd,
thanks for the advice. I also think that a platform like this is trustworthy, and model piracy would not be done by serious artists i think, especially when it comes to unique sculpts and characters that can easily be recognized.
Regarding your idea of messing up the model i am not shure if that really pays out. Modifications that are not really visible will be easy to fix, and heavy editing will crash the models appearance.
Have you every tried and proven this method?
