Until recently I've not had problems using ad blockers but in the last month http://www.telegraph.co.uk/ has become good at telling if I'm using one and not returning content if so. I wonder if this is the start of a more general fight back.

I guess as blockers stop ads downloading they just need to have something like an ad or an actual one and check if it's downloaded.

Sometimes it's a good thing. Often it gives me a few moments to pause and realise I really didn't need to read that article anyway.

Daily telegraph has recently switched to a stronger freemium model with a lot of premium content only visible to subscribers.

And you can be sure they pay a hefty sum for up-to-date anti-blocking software.
