I think I've seen this mentioned before, but why is there no rule against posting files to sites like uploaded.to which don't work on pocket pc's?
Any site can work on a PPC if you have the right plugins. Whether those plugins exist or not is either only a matter of time or being able to find them. Moreover, many people download files from their PCs, and afterwards install them to their PPCs. If you need a mirror on a different filehost, just ask for one, but I see little reason for banning the use of filehosts from which users on PPCs have trouble downloading.
