Thanks for the link.
I can't find any information as to the specifics of the service, such as how long any of the priced or free (if free is offered) tiered content stays on their servers. The only thing close to that I found was that the highest paid service allows Extended Storage and Unlimited File Size. The lower tier doesn't say anything about the subject. I still don't know what Extended Storage means. This seems to be a common problem with many large and smaller file hosts. That leaves the board with early expiring files and lots more dead links for users to click with bad results and us moderators to clean.
If you find differently and can show us, that would be helpful in any decision to approve, but as of now with what little information I can find, I'd say no but other Mods need to weigh in on it.
We have many hosts that go mostly unused as it is.
Please let us know any further information you may have and can show us.
I don't have any issues with filefox either. I download stuff on filefox pretty frequently. Having said that, I echo what Turtle said regarding not adding filefox for one user.
