Well, I just got scammed. Lesson Learned: Don't trade without first checking steamrep.

Going first with gift? Good job. o.O

Getting +rep comments are very easy, so they are in no way showing someone being honest in trades.

The Walking Dead for HIB 7 BTA sounds fishy why would you accept that :(

the guy looks like a total piece of sh1t

He looks like an arse...

That sucks, especially since TWD is a really great offer for the HIB. You sound like you've already figured it out, but yeah, always be sure to check Steamrep. As a general rule, I'd also recommend being cautious about dealing with private accounts and about trusting +rep comments on Steam profiles. Unfortunately, they're very easy to fake, or for the user to delete any negative ones.

Profile rep doesn't mean anything... He could have writen them himself. If the profile rep comments occured in a short period (like, with a few hours difference), that's a pretty obvious redflag for scammer.

Contact Steam about this, they can track everything. Describe your transaction. Post it in their fraud section.

I check SteamRep before I accept people who add me.

Contact HIB and tell them he was giving out that URL, hopefully they'll ban his Humble Account or better yet, invalidate the Steam keys.

A lesson that is taught on these forums every time someone posts one of these threads. Why couldn't you learn it then?

Comments mean nothing as rep.

Also contact steamgifts and ask them to block his account here (since he is using the site to scam people <-- and explain it to them from this point of view). Basically, he is using their Trading system to scam people.

There is also a button on his profile "Report Violation". Post your problem there as well. Basically create as much steam for Steam about this issue as possible.

+rep comments on the Steam profile are really worthless. You can delete whatever you want there yourself and just have your friends or even alt-accounts post something there. Go to steamtrades.com and do your trades there. Getting +rep there is not that easy and you always track who gave them and their rep and you can't delete -rep there yourself. And of course check steamreps before doing trades.

you should always steam rep when trading, lot's of scammers out there, and you don't just stumble upon them, they are actively seeking out people to scam. I was trading the games from bethesda collection, and like 4 scammers tried to trade with me.

Also rep in profile can easily be faked, if you want to be more through, check the reppers profile if they seem legit. Also ask them for their steamtrades profile, and you can also search steamrep forum for the guy's steamid, in case they haven't been added yet to the database.

If you get trough this things, trading can be a very successful and rewarding experience.

His profile on linkedin or FB

I know how we can all help.
1st. Block any communication with Michael_B.I.G
2nd. Report Violation: Misconduct or whatever, stating that he scammed user DJ999.
If Steam gets a lot of these report I guarantee you his account will be banned in the next few days, just from the shear number of violation reports that Steam will have to deal with :)

its just money.think it can be something much bigger. just try to smile and youll feel better .

Ok I think I found him. On LinkedID website found by Fynal. He is listed that he is a "Web/IT Director at Ksun Radio".
I check the Ksun Radio and there is a single Web/IT Director there. The persons name email and photograph is listed there. DJ999 now you can write directly to him and his friends or even give him a call!

well, always check the steam account before risky trade, now you have learned this :D

i reported him for you

Everyone can create fake accounts add them as friend and comment with them on his profile "+rep and good trader". Looking at his Steam profile comments is useless. Well you learned your lesson. If you trade, check SteamRep.

No way, man. I NEVER complete a trade until I know what I am receiving is legitimate (even if my rep is low). If you have a physical gift in your inventory, that is proof enough that you own it. You can place it in the trade window to prove you own it without actually completing the trade. Do you remember his Steam username? I'm sure the admins and everyone else would appreciate knowing who this person is. I certainly don't want him coming to SteamGifts and pulling that scamming crap here.

please report it to Steam Support and that does not go unpunished

Yea, check Steamrep next time. However, you do need to go beyond that. Check their profile by clicking on their name (don't trust a link to "their" profile because it may be someone else's). If there's not many games or the +reps they get are all from people with no/small amount of games steer far, far away from them.

So far, you're the only scammed person I've seen so far here I have sympathy for. Rest of the complainers here thought they were pulling the wool over someone's eyes before they got scammed.
