That assumption is wrong. Scammers that sell fake anti-virus assistance usually charge their victims 200-300 euros. Note, IDs don't help in those cases, since the victims happily hand over their IDs to the scammers.
And vice versa?! Sometimes I can actually *feel* the infinite number of realities unfolding simultaneously.
Stop dropping acid for a few weeks. The number of realities will feel much smaller after some time.
But Andre, it
must be true!
Because, in my reality, victims and scammers don't exchange IDs, & a weirdass app with
3.5 BTC [lol, sorry, my mistake!]
1.33 BTC 
on the books is not called an exchange. Obviously, your reality intersects mine only here, on bitcointalk.
But let us get back to the nuts and bolts. You must have missed my question, so I'll repost:
@Andre#, serious question: Assuming I wanted to trade on that exchange, and assuming (gasp! another leap of faith) that
3.5 BTC 1.3 BTC belongs to more than one bro, what happens when I buy the whole 1.3 BTC?
Do I need to send a bunch of separate money transfers to all the Anons involved, or do I just wire the whole shebang (more than 500 whole dollars!!!

) to arbitrator Anon?
No, victims and scammers don't
exchange IDs, it's only the victims who send their IDs to scammers (the opposite doesn't happen). You'll be amazed what people do after talking to them for an hour or more.
Sure, the volume is very low after this betaversion came out only a few days ago. Main thing is, it works, there are no major bugs, and trades are happening. I've done two so far, a third is pending. You tend to forget that all exchanges once started small. IMHO, Bitsquare has potential. You don't have to believe me, you can download and try it yourself:
