> Not sure Anti-ad-blocking laws are practically enforceable

An anti-ad-blocker ad would probably be easy to enforce: arrest the people making and distributing ad blockers.

However, I think the main threat is a repeal of requirements to label ads (which this technology relies on), not to ban ad-blockers outright. I bet that would cause less resistance. Quoth the OP:

> Perceptual ad-blocking, on the other hand, ignores those codes and those lists. Instead, it uses optical character recognition, design techniques, and container searches (the boxes that ads are commonly put in on a page) to detect words like "sponsored" or "close ad" that are required to appear on every ad, which is what allows it to detect and block Facebook ads.
