Some of these look similar to stuff I've seen in galleries purporting to display good modern art.
There's an asymmetry going on here... I think making bad art at this level is very easy. Most of it looks like things created by children (or young people) who are not very talented or still lack direction and practice. Perspective errors, hiding body parts that are difficult to draw for novices, uninteresting composition, garish colors... (making things more confusing: each of these "flaws" can be done on purpose by a decent artist, to make a statement).
I wonder what qualifies for inclusion in MOBA. Creating good art is difficult, but creating bad art is trivial.
Or maybe it's bad art that is noteworthy for external reasons, like Ecce Homo?
