Idk how to like ask someone about this so I'm gonna use a forum post (do I even get notifications like the mail if someone replies?)

I had a very weird thing happen recently, so I have my acc logged in, but today it kinda half disappeared.

-It was showing me ads (it shouldn't)
-Fav didn't register (as if I hadn't logged in)
-Blacklist worked tho?? my two trusty don't wanna tags were in fact blocked.
-Then I go to My Acc menu and it's apparently gone

How does this happen? How can I stop it? I don't wanna be browsing the pages then suddenly having to check if my fav registers (I use mobile so it's not on the same screen)

that's it, just got suddenly logged out but blacklist worked
