Even barring the typos , Facebook certainly doesn't need your help to communicate with or track the activity of it members.

I was just wondering if a private message I got in my facebook inbox is legitimate or not. It reads, "Elyse Renee Rucker June 16 at 4:54pm Reply

Sorry that I had to send this message. Since Facebook has recently become very popular, has become the many complaints that Facebook has become unacceptably slow. The report shows that the reason is that Facebook has a number of non-active members and, secondly,an many new Facebook members. We want to send this message to see whether you're active members or not. If you're aktiviinen, can you send this message to at least 15 users. Use the "Copy - Cut and Paste" to show that you are still active. Those who do not send this message within 2 weeks in, will be removed in order to get more space. Send this message to your friends to show me that you are still active, and do not want to be removed.

I don't think it is considering they misspelled some words and I also recall that Facebook never communicates with its members in this fashion. I just thought maybe I should let someone know in case it was a little more widespread.
