I happened to click a link that took me to the associated ~~twitter~~ X account for something I was interested in and was greeted by not one, not two, but four modern day web popups.

I know it's nothing new. I've got a couple of firefox plugins that are usually quite good at hiding this sort of nonsense, but I guess they failed me today (or, I shudder to think, there were even more that were blocked, and this is what got through)

What's the worst new/not-signed-in user experience you've encountered recently?
