One tweak to the rules and all of a sudden not only do porn sites have to verify the age of their UK visitors but also anyone connecting from something other than a residential ISP.
The more troubling thing about these laws is enforcement. The threat of fines only works against websites that map to a business entity. For anything else there will surely see a ramp up in the size of The Great British Firewall Ruleset, edited by the courts, and distributed to the Big N (5?) ISPs.
What will become of the smaller ISPs that refuse to block illegal sites?
Literally - in most of the world terms of service have no legal effect and violating them is not a crime - they are merely a declaration that the service provider feels bad if you do certain things, and if they feel bad they might decide to terminate your account.
Most of them prohibit running servers at home and using p2p apps. Has anyone here ever gotten their connection shut off for either of these?
