Some people may have received an email from 'Mari', the profile claims she is a woman from Senegal - this is not true. Mari is actually a Nigerian scammer and most likely a man.
Google his email:
You will find he leaves the same comment and many different sites. He is hoping to attain your email address. With it he can hack into any online account (such as Amazon or Ebay) and use your email to purchase merchandise using your credit card or the cards of others on your account. I work for a large internet corporation and this what we call a typical Nigerian fraud MO.
Beware of this type of scam, always google the email of anyone you 'meet' online.
Here is another scammer roaming this site; "rose baby" here with other nom de guerre elsewhere.
Google the scammer and see.
