Blacklist/Infinite Whitelist

I'd like to suggest a network blacklist option, to go along with the whitelist. Or an infinite whitelist. I use dozens of networks with my phone, and the whitelist fills up pretty quickly, but there's only a few networks that I DON'T want to use for torrents. It would be a lot easier to have the option to blacklist those few networks, rather than whitelist all the other ones I want to use.
