(This may have already been covered before by someone else. If so, I apologize ahead of time.)

Something to watch out for: someone is taking the time to create profiles and ask you to "add" their "trading account" as a friend on Steam. READ THE LINK FIRST.

Official Steam ID's are written in the format:
steamcommunity/id/#################

The PHISHING links are spelled this way:
stReamcommunity/PROFILES/################# <-- note the extra R and "profiles" intead of "id".

I've seen two already on my unusual trade posts, and many more on other people's trades.

Stay safe everyone.
