This is not a bug report.

What payment method? It is not up to us to choose.

Reports with no chats/screenshots can still be valid.

Do not call out/report users here, use the site for that.

We have strict advertisement rules, if does not matter the user's intent. We also don't have a warning system, trade closure = warning.

Like you said, it is not our fault a third-party site refers to itself by embedding a message in one of their tools.

You should be careful because if you misjudge the report and do it then the trade will be accounted for.

This was added to our dev panel on Feb 22nd, when Sneeza changes it status I'll update this thread.

If the report is valid then you should avoid trading with the user.

You should never trade with a marked scammer, items or cash. Besides putting yourself at risk you are risking your trading reputation.

It's fine, however they may try to shark you.
