What happens when a business makes a bad choice and people "unlike" en-masse? Does the counter go backwards?

Probably this has not happened much, but I do "unlike" businesses when they start to get quite spammy.

I'm pretty sure those flip things don't like to go backwards. So I'd assume an unlike would just freeze the number and absorb the next like.

The digits can spin independently. The computer driving the display can go "backwards" by just advancing the digits until the correct one is shown.
