Did I lead anyone to believe that a trade I was acting as escrow[1] for had 3 distinct DNA profiles[2]? No. Any trade that I acted as a middle man (or as some like to say "escrow"), no explicit, nor implicit statement was made by myself saying that I was not a party to the trade. Any agreement that I had sent out said something along the lines that party (b) should send a certain amount of money to a particular BTC address, once party (s) saw that such an amount was sent to that address they should send a certain amount of money and/or goods and/or services to party (b), and once party (b) is in receipt of the above mentioned currency and/or goods and/or services they should authorize the release of the funds being held to party (s) who would then receive a certain amount of BTC to the address of their choice; and in the event of a dispute I would attempt to mediate such dispute, and if it would not be abundantly clear as to what a fair resolution would be then a scam accusation would be opened to consult the overall community. Nowhere was the words "3rd" (except for potentially the date or similar), or "neutral" were used.

[1]According to the link you provided one definition of "escrow" is:
Funds were kept in my custody of a specific BTC address until at least when specified conditions were fufilled

[2]I have no idea what the DNA profiles were of any of the people I traded with, nor any of the people that I was acting as a middle man/escrow for. As I never requested, nor received their DNA profiles, and although unlikely, it is possible that a trade I engaged in only involved one DNA profile (I have no reason to believe this to be the case however).
