It won't make any sense if we have less uploads per week but at the same time, the number of visitors increase, this will stress the server anyway. A bad excuse (in the sense that it's not the only factor that causes the server stress) was used to justify the fees, but it is necessary, it's to keep the site alive. "It's definitely something new. I wonder what Rubens, Cezanne, Dali or Warhol would have said if somebody told them about a place where 90,000 artists gather?" I don't know what the others would say, but Warhol probably would say "Nevermind if you can't see all these 90,000 artists works. In 15 minutes we will have some new 90,000 artists".
