Like and Dislike *counts* are configurable in the latest Zap code (dev v19.9.27). Setting is in admin/site. It seems everybody else is doing this, including Facebook. I would've done this a few months ago but got sidetracked and the recent Facebook announcement (apparently this went live in Australia today) reminded me again.
Now if we could only get people to understand that user counts are just as much of a pissing contest as like and follower counts we might actually get somewhere.
