Maybe because the site gets then (more or less) money with our work of identification? As said before, and even if it could sound paradoxical, I'm ready to pay a kind of subscription, not to suffer jerking ads about incontinence or life insurances (I don't know what are the actual ads. I always have an anti-ad).
Better said, is it rude to ask for a kind of acknowledgement for the time and knowledge we all give to the IMCDb?

By the way:
• [...] not all ads are annoying [...]: they are all annoying for everyone, except for the webmasters who hope to earn money from them

• [...] and AdBlock's default settings and whitelisting [...]: with AdBlock "acceptable ads" evolution, some forks appeared. Moreover, there is (at least for Firefox and derivatives) some other "non-AdBlock related" anti-ad add-ons. And some home-made / work-provided proxies (Privoxy, Squid...) block advertisements too. Maybe you should use the more general "anti-ad system" name?

• your "anti-anti-ad" is a Javascript. No-Script should certainly work, then

In fact, it's just a kind of arms race: Internet users have now the anti-anti-anti-ad (doesn't work with Pale Moon. Or works only with AdBlock Plus, that I don't use?). Next move for webmasters will logically be to create an anti-anti-anti-anti-ad. As said in a lot of TV-series: "Stay tuned"
