yes, I have used it a long time ago to make transactions between acquaintances and myself. Using a trustworthy person of both parties.
I do not take fees apart from the one the bitcoin network takes, I do the mediation part for free.
I you want to try the platform you've got my profile and my references.

have a friend create a profile and you could do a transaction to him using me as a trust agent.
it is basically a 3 user transaction, if the two users confirm the transaction has been made correctly, the trust agent dont intervene.
If there is a problem the trust agent decides if the BTC transfer get complete or not.
