You can pick any complaint that is related to dA in some way (so users, community, the site, deviations, etc, etc). If we can relate it to dA it's acceptable. You can pick your own complaint or one you've seen others make.
It's very open ended. If you'd like you can note me more information and I can do my best to throw ideas your way. (Completely up to you if you use any of them, of course, and I'm not an expert in everything so not all my ideas may be good.
