Lureri/Trickery
ErovieBE CAREFUL. Most of the "women" I've been contacted by are scammers who, after sending a picture or two, want you to send them either money to pay for the air fare to come to visit you or to send them an iPhone 5 to prove your love (!). Strangely most of them has somehow been connected to Nigeria (either modelling there or working on an inheritance claim or...) eventhough they claim to be white girls (they all sent different pictures of a white girl claiming that was her, but hey, how difficult is it to find pics of white girls on the web?)
Erovie also let you register which region of your country you would like your contacts to come from, but hey, none of mine did. They all came from abroad.
Fordeler
None, unless you would like to easily depart with your money to some scammer on the web.
Ulemper
Plenty! See above.
