Kicked off the forums by advertisement

[happy medium]

I'm getting kicked off the forums by a ad that's says congratulations.
Its some kind of permanent pop up. I can't go back or do anything except close down my browser on my phone and restart.
Driving me crazy. This is the third time this year this has happened.
