point 1 still applies - use escrow
@Bitcoin-Sales: IF your offer is legitimate, then be aware that what mark113 is talking about is not true escrow. It's just a stranger with good reputation on this forum who is willing to be a middleman. Their only claim to legitimacy is "forum trust", but remember that "forum trust" is worth exactly $0.00 if he vanishes on you (e.g. dies, steals the btc, etc.).
So if you plan on doing lots of business, you'd be better off with an actual legitimate company or law firm to act as escrow/trustee.
Firstly the definition of "Escrow"
"a bond, deed, or other document kept in the custody of a third party and taking effect only when a specified condition has been fulfilled."
So it is true Escrow.
Secondly-
1) Who the hell is going to use a "law firm" for trading small amounts of bitcoin. It would have to be huge trade to justify the cost.
2) Why would a "legitimate company" be any more trustworthy than someone like OgNasty who has provided Escrow services for large amounts of bitcoins with years of history and zero problems. I would rather trust some like OgNasty than some fly by night internet escrow service.
3) You call yourself "Scam Investigator" but I note from your history you have inquired about purchasing a legendary account - usually the sign of a scammer : https://bitcointalksearch.org/topic/m.15132628
To quote you
"Their only claim to legitimacy is "forum trust", but remember that "forum trust" is worth exactly $0.00"
If that is the case why do you want to buy a legendary account?
