Do you run a Facebook Page? Heads up: your page’s “Like” count is probably going to drop a bit soon, and it’s totally not your fault.
The short version: Facebook is changing the way it’s counting likes, subtracting any accounts that have been either manually deactivated or “memorialized” after its owner passed. It’s something that probably should have been done since the beginning — but since it wasn’t, it’d be easy to think your Likes had dropped because of something you’d done.
One thing that’s important to note: it seems that this only accounts for profiles that have been manually deactivated. Likes from profiles that could be considered “inactive” because the user just hasn’t logged in for a while will continue to count.
