TV ads are targeted on the basis of the program and the transmission time, from that, they work out a probably audience and put up ads for that audience, they do the same for ads in magazines and newspapers as the ads vary with the product.

Neither do web adverts.
I have been paid to watch tv ads - a few times to attend a location and give my responses to the ads, but mostly to have a ratings box in the house.
Being paid to view ads in that context (attending a location, giving feedback, having a ratings box etc) is a different kettle of fish than you simply being a user of a website that uses adverts. They pay you because they want your feedback. I'm sure there are websites that would happily pay you to show you web adverts and then ask for your opinion.
LXF or the third party advertisers are not asking for your opinion on their adverts so should not be paying you; and as a visitor to the site you have no right to ask for payment.
