It seems this extension could be tweaked to only operate on sites with high Alexa rankings or similar to avoid this problem. That would probably be a good idea, because you make a good point.

Or, it could even have two "modes": a "carpet bombing" mode for high Alexa sites that clicks everything, and as you decrease in popularity, it increasingly begins to simulate real user behavior.

That would simultaneously disrupt the system for the big players and, hopefully, get extra revenue for the little guys.
