Well since you obviously agree on the principle of rewritable cookies
You must have misread my comment. I have never agreed on rewritable cookies. What I meant was that I don’t have a problem with a cookie set to expire within a week or two. To me – whether the cookie will expire in two weeks or it could be rewritten in two weeks makes no difference. If a player I’ve refered doesn’t sign within 2 weeks, I guess I don’t have a right to bitch 
But I don’t approve of the option to re-write my cookie virtually instantly.
I guess it is a matter of time, but I don’t see the point you are trying to make. My point is that BET365 never disclosed that the cookie will be re-written, on the contrary, according to the their T&C, the player is tracked to you for the 45 days the cookie is active. I find this deceiving and I would’ve never signed up with them if they did not misled me ( I do read T&Cs).
Here is a question to Bet 365: Let’s say a player opens a review of Bet 365 on the Gooners and My Website in two new tabs, bu the same IE session. The player clicks on Bet 365 link on My Website and then clicks on Bet 365 on Gooners. Then the player closes all windows and goes directly to Bet365 dot com. To whom will that player belong???
I don’t think life-time cookies are a good idea, but I would not have problem with them since no one keeps a computer for 2 years Virus scans also have the tendency of deleting cookies.
