Disclaimer - I am hesitant to complain because this is an amazing site with fabulous content and a charming community that I love. You guys deserve to be compensated for your labour of love and I will modify my behaviour if I must!
Perhaps I am the only person who does this, but - I often accidentally leave my mouse cursor directly overtop of the "hover to experience" ads while I am writing a post or reading a thread. Then, seemingly out of nowhere, there's a giant video overtop of whatever I was reading or writing. It is jarring and not a great experience from a user's perspective.
