Their reviewing process for selling photos is massacre, I got 5% acceptance rate now, vs 98% on major agencies.
Plus you have to pay yearly fee so they can make money from your content, pure joke.

I made a comment or a thread regarding this site. I sold 7 pics here. All were purchased on the same day. I only made 7 cents. So as one person on this thread had said "You heard wrong". I will no longer waste my time uploading my pics here.

Is there any reason to leave your property at 500px / Visual China Group?  Is there any upside at all?  If not why stay?
