You may also get accidentally get your own website blacklisted or moved to a lower RPM tier, or provoke shadow-ban websites that you like to visit, or... generate more ad revenue for them.
Any jurisdiction where this is supposedly illegal, it hasn't been court tested seriously.*
Per your link: "What you're describing is essentially the extension AdNauseam. So far they have not had any legal troubles, but they technically could." That stance or an assertion it's not illegal is consistent throughout the thread, provided you aren't clicking your own ads.
"The industry" thinks you shouldn't be allowed to fast forward your own VCR through an ad either. They can take a flying .. lesson.
* Disclaimer: I don't know if that's true, but it sounds true.
No, the illegal-ness doesn't come from the clicking, it comes from the fact you're clicking with the intention of defrauding someone. That's also why filling out a credit card application isn't illegal, but filling out the same credit card application with phony details is.
You're defrauding nobody. People purchase visibility and clicks when they purchase advertising. not conversions or sales.
Again, you're ignoring intent in all of this. It's not illegal to default on a loan, or even to refuse to pay it back (eg. bankruptcy), but it is illegal to take out a loan with the specific intent to not pay it back (eg. if you know you're planning on declare bankruptcy right afterwards).
