Well those questions can be (possibly) answered through this guide.

First off, TF2 outpost use to be a scam-bot free trading plaza but recently, someone has implemented scammer bots that provide you with fake link claiming to be the right one in attempt to hijack your Steam accout. Now not only this is malicious, it's downright wrong to those who have fallen for it. Someone I know almost DID fall for it but I stopped him at the last second and told him to change his password.

So how to detect/stop them you may ask? Well I'll try my best to tell you.

So recently I discovered that most of these scammer bots target ALL TRADES, and adjust to the item accordingly:


Now I specifically said it's not for sale and if "traders" add you regardless even if you told them it's not for sale and you're not looking for them to add you--I don't know if you actually do make a trade saying it's not for sale--then it's obviously a scammer bot, or a silly person who didn't read the notes.

If you so happened to inspect the person's account look out for these key things:

• 1: Their account is private
  
• 2: They obviously don't use Steam often/have a low steam level.
  
• 3: They can't possibly trade for that item (Unusuals for instance)

In this instance, the "person's" account is private, a good sign that they're a scammer bot.

If you accepted the friend request they'll most likely send you something like this (with possible grammar issues):

And if it IS fake, this will show up:
Do what Steam has to say at this point, unless you are 100% absolutely sure you know it's not a hijacking website--or if you really want to lose your account...

If the person who is "trading" you matches these few key characteristics, immediately remove report them for attempted hijacking/phising and remove them from your friends list (preferably block them)

But if you so happened to fall for it and go to the website, have no fear, they can't do anything if you don't put any information to do so as it requires your user and password, as well as the few methods to get through steam guard. if you didn't do anything like this, you're in the clear. If you're paranoid like me thinking they have some kind of fancy-shmancy hijacking tool that can steal your account if you click on it, you can change your password, if you'd like; better safe than sorry.

Unfortunately the only thing you CAN do is go to their profile and report them:

When doing so, provide as much information as you can. Just in case, if you're sending the link that the scammer provided, put some spaces just in case if Steam thinks YOU are the scammer.

As for a fail-safe, block them if you know they have nothing to ever do with you.

Keep in mind, there are some of those poor saps that have fallen for this trick, lost their account, and turned into a scammer bot--yes, a scammer bot.

This is a short step (unless you want me to teach you how to report the person) for the sake it's only two steps.

You may be wondering after garnering the knowledge on the characteristics and methods of said scammer bots, "How do I make ABSOLUTELY SURE that I won't get scammed just in case if I am to sleepy and fall for it?"

Well, it's simple, go to sleep--more

Okay, maybe not that simple because if you're like me, it's hard to sleep

Okay, let's actually get serious; get some sleep medication

Okay! Okay. Here's the real thing (I'm sorry ;-;):
One of the ways I know--on top of seeing the link errors--is through a script to warn you even after you've gone through the steam warning, here's the link: http://psteamcommunity.yuanyoumao.com/groups/tf2outpost/discussions/0/864974467246310286/

Many thanks to the person (Derongan) who made the script, it helps those silly people who aren't as careful as some others and for being there just in case :)

This is pretty much the final step on trying to stop them, there's nothing we can do than crossing our fingers and hope Steam will make things better, although they can only ban them.

So you made it this far, I'm surprised you made it through my horrible guide-making (thank you for baring it).

Anyways, thanks for reading this guide, I hope this will prevent those who are new to Unusual trading or trading in general in TF2 Outpost, from being scammed from their account.

Extra notes:

Some of these scammer bots have been hijacked from their owner and turned into a bot, ruining their reputation in trading. To those who have been hijacked and trying to get back their account, good luck to you.

If you noticed the profile looks well-polished and put into their own masterpiece, DO report them but let Steam know that the account has possibly been hijacked from their rightful owner and ask to suspend the account until it has been returned to their rightful owner.

So, that's it for now everyone, thanks for reading, stay safe and stay fluffy fellas

Recently, bots have been sending image links to imgur or something like that when, upon clicking, will download the "image."

Do Not Download or Open It

The "image" is actually a screensaver executable which holds some form of coding that can and will steal your stream account. Please be wary when a random stranger gives you an image instead of a fake steam link.
