Heres another chestnut thrown into the mix? How about every time you log on you get assigned a different IP number? Or rather the same IP number but not your IP number? Come Again? WiFi credit cards display the IP number of the Company headquarters only. Thus if you go online using a Vodafone PAYG sim net card IP will awlays be and read Vodaphone company HQ address and no other. So it always amuses me when some amateur cyber watchdog comes on and says 'we know yer IP address'& can link it to yer contract and payment address.... I do not think Vodafones HQ IP address can be 'blocked'either? BT and Virgin have conducted for years a concerted campaign of harassment through millions of letter boxes with their unwanted promotional mailings (unstoppable as they delivered by Royal Mail along with regular mail and cant be cancelled) in a misguided effort to get as many dopes online and contracted as possible. Then these self same corporations eg BT who are traditionally a virtual arm of The Police and Security Services and upholder of public morals and snooping and wire and phone taps have all your usuage and data at their HQ ready to hand over! As well as having you tied into an expensive and stressful monthly debt contract for a Broadband service that doesn't even deliver what its promised! Yuk.
