Not I wouldn't mind, no, but it would be my own fault to an extent, so while annoyed (at myself for being gullible more than anything), I would see that.
Take it off an dating site, and say he's sat on a pier doing pencil drawings, for example. If you ask him to draw you, and he does and you don't like it (Whether he intends to be nasty or is just a crap artist). It's not his fault you asked him to draw you. He might have thought you'd like it.
Even if he knew he wasn't a good artist, he might have thought you'd find it funny.
I can see why, on a dating site with tonnes of generic people, he could maybe think that making a woman laugh would make him stand out from the crowd?
