Keeping up with changes in social media can be a challenge. I like to think I'm pretty up-to-date on most features, but for the life of me, I can't figure this one out. Have you seen it?

To the far right of the comments, there seems to be a counter. It looks pretty similar to YikYak, an app where you could up-vote or down-vote posts. If the post reached a certain number of down-votes, the app would erase it.

So far, this feature has only popped up on some Facebook posts I've seen. But every time I forget about it, the feature pops up again.

Have you seen this in the comments of your posts? Have you tried it? Help a confused millennial out here!
