Still happening to me. Even happened a while ago where I was trying to log out and it said "you have to log in to do that action" or something like that.
I'll test this later on a different computer, but I am 99.99% sure that nothing on my end has changed. I'm accessing everything the same what that I have for many years. I do hope that other people can pipe in and say if they've seen the same thing or not.
You caught a nasty bug from those porn sites!
