Re-reading the original post, it seems that the “argument” started over someone asking why people wouldn’t get certificates. That’s something we get quite a bit on here, people asking for look ups because they don’t want to, or can’t afford to get certificates. So my guess, as has been stated several times, that it is the same with the OP on FB, they want to complete their tree as cheaply as possible by using information posted by others.
It seems Pharma, that you are actually adding sources to your tree, but not in the form they want ie one they can download. If you put a on reference that you understand eg as a comment “see death certificate and burial record from NBI” that is good enough. That shows the records are available and tells anyone else where to look, if they can be bothered!
As a couple of people have asked, what is the FB page where this happened? Maybe the OP poster there needs a few Rootschatters to chip in!
In the end, ask yourself, who would you rather listen to and take advice from, those of us on a dedicated site such as RC or someone on a FB page who is obviously out to complete their tree as quickly and cheaply as possible by using other people’s trees, rather than do all the research themselves. No choice in my opinion.
Continue to your tree as YOU want to and ignore others.
