THIEF!!!!!! ALL THIEF!!!!!!

Todays steam full with unsuccessful scam, usually newbie player get caught by those scamer who literally disguise them self as a guy who want trade some good item. Scamer usually got their prey from DOTA2LOUNGE cos a lot of people in there were interesting to trade such as items or other bundle.
they usually add u and offer u "hey i want to have a good trade, please open this website : www.steamcomunity.com/fuckyourself" as the example. even though that website is named "steamcomunity" but steam actually doesnt give the steam guard on the website and not powered by steam it self. unfortunately after u open it, u need to login ur steam account on that unsecured website, plus u need to verify your account on that website

how to know its a scam?
1. usually the account who add u and persuade u to open that kinda web is actually a fake account, and rarely been used, look at the inventory and their friends, do they have friend? if the dont, u better kick them out, if he has, stay vigilance look at their invent or account lvl, usually an account that has been played must be lvl 1 or more
2. take a look the way he ask u, if they straight to the main purpose, usually its a spam message, kinda like a bot running that chat.
3. when you ask them they never reply
be careful and be aware for those message, u dont want ur items gone, do you?
if u have other tips, please tell me
