With the immense popularity of FIFA’s Ultimate Team and the hundreds of millions of dollars spent by players on this mode, there is a shady underbelly of people out there that want to get their hands on some of that money. Remember, EA Sports will never ask you for your password through e-mail or via message on either PSN or Xbox Live.
If you’re a Twitter user, only interact with @EASPORTSFIFA or their Verified accounts from other countries. When you do mention them, there is a good chance that a bot with a made up account will message you back saying something along the lines of “Click here to redeem your free Ultimate Team Packs” with a link. These links lead to non-EA Sports sites that will take your username and password and can wipe your account of all its points, cards and coins. Yikes! Don't do it.
