does Wooacry steal art?

I thought i had found a new way to possibly make money using Wooacry, but my mother is convinced that once i upload my art theyre gonna steal it and sue me. this does sound irrational but i was wondering if anyone can vouch for them?

I really dont think theyre gonna do that and i really want to make money so if anyone has used the site before could you give a completely honest review? i cant find anything online abt art theft, only reviews abt the product so please lmk what you think!
