If you haven’t already, it’s always a good idea to turn on two-factor authentication and change your password. Even better, you can review what devices are logged into your Instagram account in Meta’s Accounts Center.

That is not the most obvious safety advice here engadget…

As a huge fan at the time, I agree with OP.

However, I cannot agree with other commenters that Karl would be an actor or “in on the joke”. In the early XFM shows he seeps into the show ever so slightly and awkwardly. Ricky tries to pull him in, but his contributions to those first 5 to 10 episodes seem hesitant, timid and minimal. It just does not feel scripted or even discussed beforehand.
