Pop up

Is anyone else having trouble with a pop up from a well know telephone company. It pops up when I am looking at ‘I am on’. When I close it because I do not want to enter the competition, it kicks me out of Gransnet. I tried to include its name in the title but it kicked me out when I did that! Its name has two initials, the first is the second letter of the alphabet and the second is something you drink with a slice of cake! ( I did not want to risk being kicked out of the site again by typing the name. )
