I'd expect such websites to communicate it, though, and do the minimum of work to prevent me from entering with ad blocker on. I'm fine with paywalls, and even "disable your ad blocker" walls - they're up-front, and in agreement with spirit of the HTTP protocol.

Much like cinemas. If I try to bring in food I didn't bought at the cinema store, I will be stopped at ticket check and refused entry. Also, the cinema doesn't require me to buy food as a condition for watching the movie. If they did, I'd consider it the price of entry.

What current ad-loaded websites are doing is the equivalent of letting you in to watch a movie, and then having someone come to you as you're watching, and poke you and yell at you because you didn't buy anything at the store.

> They can call the cops and have you arrested for accessing the theatre in contravention of the rule.

I've never heard of a cinema calling cops on people who snuck in food into the theatre. Is that US-specific?
