Well i have a theory that most of you do not like to hear.
Its because 90% of uploaders are unprofessional kids.When they dont get 10+ sales per week they change host.After 1-2 weeks again.Downloaders are confused if they should buy PA or not.Thats why the highest rates on sales getting people with their own sites.Only there they can be somewhat confident that they can dl for 1-3 month without any problems.
Remember Oron.Oron was everywhere and everybody was getting sales.Go one host.Dont switch.Important for forum uploaders.Once you switch you will anger your previous premiums,dont await their come back to you.
Shit you upload:dont waste time to upload new releases when your a small uploader.New releases are everywhere worth only for sites with many visitors.or be quick.faster than light.when your not,upload unique staff.
So my theory: - go one host
-dont switch
-upload unique staff
-be patient (or get a real job)
