They pay on 30 working days or 60 normal days, the time of payments will be reduced step by step, but the most important is that they pay, they are honest and if you have any problem, send them a pm by fb, they answer to me sometimes.
The problem with servers is that they are working on them for us, to can upload/download better, you can see are some servers with problems, or servers with no counting downloads/earnings and they are trying to fix all.
I dont know how is working this year with sales I am on PPD but from 2 months I had only a sale, I have over 600 downloads daily , my rank wasnt update for a long time, I will try to get more sales working harder, I dont know how is working but they are counting correct, I had files in december on s16 30% of my files, I lost all earnings on 30% of the files at s16 from 15th december because s16 is not counting downloads, this can be a reason from where my rank dropped I hope they will fix all problems, dont forget Bitshare still pay and had a decent speed on download.
