If you know he is a scammer and you trade with him, there is a huge chance that you will be marked on SteamRep as well.

Don't take that risk though and refuse to trade with him. Simple.

thx for info

But, that doesn't happen if the person i trade is just banned right?

Trading with a banned user on TF2OP is fine, trading with a marked scammer on Steamrep however is not. There are lots of reasons you can get banned for on TF2OP, that doesn't make you a scammer.

Make sure you always check the Steamrep profile of who you're trading with when doing high tier trades and you'll be fine.

Someone was actually trying to sell me a Gift Wrap the other day and I looked at him profile and things and It didn't seem right so I didn't trade with him and lucky I didn't because that Gift Wrap was scammed and he got marked as a scammer a few days later.

Some people are banned on tf2op as alt/scammer, but not steamrep.

Helen can tag scammers on Steamrep so if someone gets banned on Outpost for scamming they will most likely get tagged on Steamrep as well.

Regardless of that, trading with scammers is a punishable offense. I was merely replying to inuyasha who was concerned about trading with people banned on Outpost. It's ok to trade with banned users as long as they are not scammers.

I have seen many times users that are marked on tf2op, but not steamrep. It should be better integrated.

Also problem with SR is, is that many hijackers are not marked there. All obvious alts selling phished goods are not marked there. But I understand trading with them is also punishable.

I'd like to point out part of the rules:

No trading with scammer alts. We do not encourage our users trading with scammers, and you should be careful to not trade with obvious alternate accounts of scammers. Please check the user's Steam profile and SteamRep status before trading with them.

That's Steamrep policy, they do not mark hijackers because it's a pointless cat and mouse game. All the accounts they use are either throwaway accounts, which by the time they would get tagged are no longer in use or hijacked accounts that are recovered in a matter of hours/days. You may see hijacked accounts temporarily tagged to warn users not to trade with what may otherwise look like a legit account.

If that's what you mean about banned TF2OP scammers not being tagged then you're right, however it should be obvious that they're fishy and you should never trade with them because if you do you're only helping them and become part of the problem.
