I am not aware of Facebook the company having a samples category. I do know that there are several sample pages on Facebook. Some of them are legit and some of them are scams that get very annoying very fast. A lot of them actually are very annoying. Most sample pages want you to share their content or to comment on their posts so it'll show on your wall. I have tried a few of them. So far no luck, I just wasted my time. I unfollowed them very quickly. I am not going to stay on Facebook all day long to be the top 10 to like, comment, or share any of their posts. I have way too much to do. But of course, not all are that way. My best advice is to check out the pages and do a trail run on them. Do not give out your personal information unless you know that they are who they say they are. I hope this is helpful to you.
