If you are a Twitter and you got a DM (Direct Message) from someone you follow which is similar to this one, avoid clicking on the link. It's a scam.
If you do click on the link, it will take you to a website which looks like Twitter, but it's not Twitter. It's run by scammers. They will ask that you enter your Twitter username and password, which they then use to take over your account and send similar messages to followers. That's how the scam spreads around.
Here is the website that steals your credentials. It looks like Twitter, but it's not. How to tell? Look at the address bar, which shows the website you are on. It doesn't show twitter.com. It shows tvivvter.com. It's also not secure - the green lock is not there.
Who owns tvivvter.com? According to the records, a Shanghainese named "Chen Wen" . Maybe. And maybe not.
If you are a victim, follow Twitter's guide to "My Account has been compromised". And this time, take a look at the address bar!
