I've worked hard to assure that my research is accurate and well-documented. I finally tired of those who copied documents, photos, etc., from my tree to the WRONG person/family/century.
I still have a tree with all the photos/documents/etc., but it is private. I also have a public tree with all the source records attached.
It is a little more work for me to maintain 2 trees - but only a little. It's worth it to me to avoid the aggravation of seeing that someone has once again attached the tintype of my 2nd great grandfather to another person with a similar name in a different century/country/family.
