So now FPH have changed the max download limit from 400mb to 300mb for free users

You should keep it as 400mb... to keep changing the max download limit is not a good idea as uploaders have now got loads of files 300mb+ that can't be downloaded unless people either register or go premium which will only result in your host being banned on many forums (and lose you premium sales).

Many forums i post on have rules that a download link can only be posted if people can download it without having to register, so all 300mb+ files now break the rules (thanks). How long before you change it to 200mb or a crappy 100mb like Filehost.ws.

I know you need sales to survive but to keep changing the max download limit is not the way to do it. You should keep it as 400mb and maybe limit the number of downloads a free user can download in a 24 hour period to just 2 or 3 (they will more likely go premium that way).
