AdNauseam does just that. It clicks the adds before blocking them (possible to whitelist non-tracking adds). It's a fork of uBlock and what I replaced the uBlock with on my phone and PC.

Sadly, it doesn't do clicking in the private browsing mode, which I usually use not to crowd the browsing history with hn and other forums' articles.

Are you sure you haven't just forgotten to enable the extension in private browsing? Their FAQ suggests that you can enable it for private browsing, but it's not on by default.

I'd be worried I'd get blacklisted by cloudflare etc with maximum prejudice.
