Millions fall for scam on Facebook within minutes

So who can analyze the following script: https://www.facebook.com / chespier.moranseverino.7/posts/1435336293368456?notif_t=comment_mention

I'm pretty confident that it's save to visit but for some extra paranoia I added spaces after ".com".

A friend "mentioned" me and as it appears, within minutes, millions were "mentioned". Actually 1.6Million comments were submitted to that post by time of writing this. Any clues what the script does?
