Then don't? Just ask for a donation if you think the website is useful and enjoyable (I'm cross referencing posts alot in this article, but see what I said earlier about NexusMods).
I don't expect people will want to pay just to log into your site and that's not a business model they want to use. But if I can pay an optional $0.50C for every site I regularly frequent to skip their ads. Which assists them in providing a web service or content I want to consume. That's the road I will take.
I want to help the content creators but I won't consume their advertisement material.
I guess that's probably the most polite response, at least.
The main motivation I can see for an ad blocker-blocker-blocker would be for like, if the ad-blocker-blocker has claims than using an ad-blocker is immoral. Because, well, it could be sorta insulting.
But if it's just a statement of like, "don't use our website with an ad blocker please" (and not displaying the content), then, using an ad-(blocker^3) is I think probably rather rude.
Probably not outside of one's rights, but still, rude.
