This is a general SCAM Warning for all STEAM users!

If you get a message from a friend that goes like shown below it is a rebot trying to get you to sign in on a fake steam website to steal your user data.
Do not enter your data on any other than the actual Website of the company, this goes for Steam, Paypal and Facebook and other sites.

Do not visit the website and do not enter your data, your account will be used to send this same or similar messages to all your friends trying to scam them as well.

To everyone who received a message like that from my account: I am sorry. I fell for this scam and my account got taken over for a short time.

UPDATE:
This scamming just got a whole lot more sophisticated.
Be very wary of steam users claiming they made a accidental false report against your profile, directing you to contact "Steam Support" through Discord.
The associated Discord profile looks real at first sight but is fake too.
As explained above, NEVER EVER give out your data or anything that can be used to login to your account on any site or service other than the verified OFFICIAL one.
If they claim to be from Steam Support let them verify it through official Steam/Valve channels like the steam platform or at the very least an email from the official Steam Support account.
Do not trust any screenshot or other immage they send you, no matter how official it may look. All those can easily be counterfeited.

There are several YouTube videos about this scam, i found some just searching YouYube for "steam phishing scam".
they explain the scam better than i can do here.
