One time they told me I had 3 days left to enjoy YouTube with my ad blocker, and then I would have to buy premium, or they would just lock me out of the site. I was like “welp, it had a good run, I guess that’s it for ol’ YouTube.”

But then the 3 days went buy and nothing ever came of it.

That tactic probably did get them some preemptive subscriptions though, unfortunately.
