First: this will affect only quite a few posters. Second: this does NOT limit the number of photos you can post without storing originals. Now to the point. Since (some of) you do not quite understand what is the point of storing originals we are now introducing a space limit for this storage. Right now some of you guys use upto 90Gb of our server space. And this is FREE for you but never was for us. So now on without special permission from us you are not allowed to store more than 2Gb of originals. Again, this does NOT limit the number of photos you can post without storing originals.
PS: Please note that creating multiply accounts to bypass this restriction will get all connected accounts locked out.
UPDATED March 2017: We raised the above limit to 10Gb per user.
