Luke, then as far as I can gather, if you don't pursue or actively monitor content by your clients, you as a host are in the clear in these new 2257 regs. However, if you've showed a pattern of viewing client content and shutting the client down without a demand from law enforcement, you would be showing that you do actively control your clients content and enforce your TOS.

Keep your shades on And don't go lookin' till the wind blows one way or the other.
