I worked through this with Amor, and it has to do with when Facebook switched to short URLs and usernames. Read the following from our development discussion this is like this because not everyone has a facebook username. With insta and snapchat, you must have a username so we can just prepend the rest of the URL to people's usernames and make it a link. With facebook, you might have a username if you created one yourself but you also might not. This might be confusing for someone without a username because they either won't know what to put in the field or they put in their full facebook URL and the link would be really messed up without validation.

We could get around this by saying "Please enter your facebook username or user ID" but the process of getting that user ID seems too convoluted for regular users: @christiansander1 think the best way to solve this for now is to just paste in your entire facebook profile URL. That way it will be a link.
