Can you explain more, I mean multi-sig is a good idea but you need to trust the third party if it is 1 out of 3 and also it must be ensured that the webmaster does not know or ْgenerate addresses.

why you only have tor version on the Tor network, It is to avoid DDoS attacks and privacy, which are not necessary for a new website trying to gain trust.

Escrow needs to be trusted by a third party who cannot be anonymous.
