well I do understand but I have mentioned that we can use some PATTERNS (like leaf, Emblems, ribbons etc) on vintage stuff (not direct cliparts or stock images from google). And in my profile some of my gig samples are templates which I have got years back and it is approved by Fiverr's editorial team which they asked for. I provided them the Source files of my designs along with premium License of the designs which includes copyrights for fair use.
But if the buyer is not satisfied or happy with the work, then he/she can raise a dispute and cancel the order as simple as that.
