By suspending accounts and not offering a different way to participate to improve, is not very encouraging of designers to want to come back and participate.
Funny how I was in the running to win one contest, and received very good feedback from another and now somehow after 2 years, the quality of my work is what? Bahahahaha
With sites like designhill, designcrowd, there is a whole world where I would rather participate and I do and make money.
Don't bother with 99designs, not like they pay benefits or support people working.
