@Those recommending TrackMeNot
For those recommending Firefox + TMN, this will NOT stop them profiling you, nor will it stop them tracking you (I suspect they'll just filter out requests to search engines if enough people start doing this). Identifying fake requests is alot easier than some of you seem to think ;o)
If you want to stop them tracking/profiling you, use a proxy (i.e. Tor) .... and even then, make sure the traffic is encrypted for the proxy BEFORE it leaves your computer/network (i.e. SSH) .... and HOLY CHOCOLATE CAKES BATMAN - you can use shells other than FireFox with these!!!
@ the person that mentioned the government petition, ignore it - they'll not give a hoot ....
Best way to stop them doing this is to vote with your cash and move providers (i.e. to one that IS NOT selling your data). I'm currently with PlusNet, who claim may not be introducing this - which is also false (their RIN customers WILL be affected by this), and I doubt PN themselves will not be going for this themselves as they've been more interested in cash than customers for quite a while now (and I don't mean since being taken over by BT either).
For those wondering, whether you opt out, use TMN, your provider is a BT "reseller" (e.g. PN, AOHell, Tiscali, TalkTalk etc etc) (by reseller, I mean they still require you have a BT line, so it's obvious they go through BT pipes) - if your traffic is not encrypted before it leaves your end, it's going to go through BT/cable pipes, so it'll be trivial for them to profile you (they've actually been doing this for years - whether or not they previously sold it to third parties is debatable).
Can you end your contract without penalty if your ISP is using Phorm? yes you can. Your ISP has changed your contract without notifying you first and thus, has broken the contract themselves, thus all you need to do is write to them (ALWAYS put this type of thing in writing), and give them notice of their breach of contract and your subsequent cancelling of such contract.
A simple;
"Dear Sir/Madam,
Due to your introducing Phorm on your network, without giving me prior notice or requiring my written consent, you have breached our contract and thus made it void. I am therefor cancelling my subscription to [ISP NAME] immediately and without penalty."
I did the same to end my Tiscali and AOL contracts (though this was for a breach of contract, it had nothing to do with their tracking or selling me data or browsing habits).
Anywho, Top Gear is on ....... so I'm gonna stop rambling and caboot .....
