Like you I draw the line between the 2 self explanatory examples you used.
In going further, the problem I see when tolerating the publication of bill-paid-parts-project is that eventually it leads many others to unauthorized sources that produces with no limits and in total disrespect to brand’s patrimony and intellectual properties
As you also said, there are many watches forums out there, each serving a philosophy. I am not a snob nor did I became one, but I am surprised and find it very odd to find bill-paid-parts-projects as here discussed to be here welcome.
I must say that I am a guest in this house, I highly value its community and respect everyone opinions and positions.
