Hi Alexander,
My original message was a bit rambling....
I have never invited anyone to my tree. When it was initially a public tree - before I actually had any info - I knew people could just copy it but I didn't mind - after all, there was nothing on there that couldn't be found on A******y.
I made it private once I added more info, and I didn't 'invite' anyone as it was purely for my family (there isn't anyone else looking in to our specific family, and I added info that is not readily available on the internet or to people who are not close family members)
The people who copied from my tree did not contact me at all to ask permission - however as it was listed accidentally as 'public', they didn't have to - it's just polite to check, but not mandatory. There are lots of mentions on here from people who have had their public trees copied, and even the photos attached to them, without having been asked permission.
A******y say that they will try to blank out any details of people they believe to be living in both public and private trees, including names, however I have seen public trees listing people born within the past 20 years with no death date - and the full info shows up.
If your tree is set to private, no-one at all should be able to see any details bar the name of the person (and supposedly not even this if they are living). Dates and other details are blanked out, with a message saying 'this person has asked us to keep their tree private... contact them etc).
If you don't even want your tree to come up in search options, go in to privacy settings, make your tree private, and tick the box below which says something like 'don't include this tree in search results'. A******y don't recommend this, as they say it will stop people from contacting you who may have vital info - but if you are happy not to be contacted by other researchers, it stops you getting unwanted messages.
Mine was a very unlucky glitch. When I updated my settings, A******y's server which contains all the info did not receive this request, and so left it public despite it saying private in my settings.
If you think that your tree might still be 'public' although you listed it as private, try logging out completely of A*******y and searching for someone in your tree. If you have requested your tree not to come up in search results, you should not see it listed in the results. If you have requested it stay private but can be listed in search results, when it comes up it will say 'private' as mentioned before.
If your tree is private but you notice anything strange, such as in the 'news feed' on the home page, other users adding things to their trees straight after you have, or adding things which you have personally scanned and added (i.e. not available on A******Y), contact A******y.
I didn't mean to 'scaremonger', and I will be keeping my tree online for now having paid for a subscription. But I was not entirely reassured by A******y's comment that they often have problems with their servers not updating info. I thought everyone should be aware, just so they could check this hasn't happened to them.
I have now been reassured that my tree is private and does not come up in searches, so I am happy to keep it on there.
I hope this answers your Q's
Alice
