We've talked about bad models, but what about bad rigging? For example, pic related is a model rigged by KevinX, who feels like a rigger that does things cheap. He also has terrible tendencies that I've noticed for quite a while: such as:

-Copy/paste rigging on most models done by him
-Slight errors such as boobs moving like jello, or Henya having crazy eyes early on when her schoolgirl outfit debuted
-His tendency to have a chibi mode on every recent model, making it look like an even more deformed bratz babyz doll. It looks really stupid on a good looking model and brings them down whenever it turns into a child suffer from hydrocephalus. Also is it just me or does Kevin seems to like children a bit much with making chibi modes for even the sexy models? Real pedophile vibes I'm sensing.
-Also, there is the "secret" ahegao toggle, which looks dumb and possibly a sign that the rigger might be a sexual deviant.

Apart from my example, any more case of bad rigging?
