There’s yet another of those posts doing the rounds saying FB is going to delete inactive users and therefore reduce the number of likes in your page. These types of posts are either spam or hoaxes.
If Facebook was planning such an exercise, it would be announced in their newsroom, via a press release. No communication comes out of any corporate, let alone one the size of FB, without being vetted by the Media Relations team.
The easiest way to check if something is genuine, is to look at the FB newsroom, and then google FB hoax and 99 times out of 100 you’ll find a reference to something either current or that was doing the rounds years ago.
You can now report such posts - see http://newsroom.fb.com/news/2015/01/news-feed-fyi-showing-fewer-hoaxes/ for info on how you can.
Hope this alleviates any concerns other Folksyers may have.
