Have you ever been randomly requested to friend a Steam user where they ask you this sentence below?

This is just an example that I've been asked similarly:

• " Hello, my friend can't add you, add him please. He want to offer good trade
  steamcomnnunltl.com/id/Pyroman216 "

Most phishers duplicate other users' profile links or even sites, so be advised.

The SITE they're trying to get you to go on is called a " Phishing Site ". The site's aim is to try and obtain any information about your Steam Account.

• ALWAYS CHECK THE STEAM URL CAREFULLY before you add a certain Steam User.
• ALWAYS COMPARE THE STEAM URL to the official Steam URL
• OFFICIAL STEAM URL: [ steamcommunity.com ]
• UN-OFFICIAL STEAM URL: [ steamcommunitriy.com / steamcomnnunltl.com / steammcommunity.com / steamcomunity.com / steamcommunity.cm ]

What you should NOT DO:

• 1) Trust them
• 2) Click the duplicated site
• 3) Add the user
• 4) Login at the duplicated site

What you should DO:

• 1) Ignore
• 2) Block
• 3) Report
• 4) Remove

I advice you to change your password at least every 1-2 months.

• These users are involved in either scamming, phishing, impersonating and sharking!
