How to fight ad blockers?

[johnnybg]

Since web ad-blocking software is in great expansion these days, and every day new features arrive, I wonder what we as advertisers can do to fight it?

Mostly all firewalls offer ad blocking. I personally use Zone Alarm Pro 4.0.123 which succesfully removes 90% banners from pages I visit. BTW I recommend all webmasters to check their pages with some ad-blocking software because you may find yourself pretty shocked when you see all your advertising gone...

New feature of some ad-blockers is removal of text advertisements. Since only way to hide your text ads is by using some script language, and most majot TGPS/LLs don't find use of invisible links appropriate, what can a webmaster do?

I also found that some of graphics banners are left intact with ZA, but I'm not sure about others... Some odd size banners are still alive but I don't know how long will they last.

Also, I wander if this kind of censorship is allowed by US laws and constitution? I'm not from US so I'm just asking for your oppinion.
