I almost got scammed on twitter by a fake account. Scammers are setting up fake accounts pretending to be other people/ICO's/Tokens. It's very tricky if you are not paying attention. Make sure you check spelling on all names to be correct. Be careful who you give your info to. Even if it's just your email address. Scammers will not stop scamming so watch out and pay close attention to what you are signing up for. Good Luck everyone and be safe!
It's not only about Twitter. A very big problem nowadays is fake Telegram accounts of projects admins who try to make people send money to fake wallets by promising ICO discounts. No later than yesterday I saw such an example in of the project groups - community member was told that we would get a 40% discount is he sends Eth to the scammer's wallet. Just remember that admins never send pm first unless preliminary agreed.
