I have been using GR since 2002 and over the years have exchanged information with many descendants of both my and my husbands relations.
In the early days some would put family members on, down to children born in the last few years.Their Trees are still open to me and now the majority are more circumspect.
I still get some genuine requests, but the ones whom I contact and have always made me very cross, are those who cannot be bothered to say "sorry, this is not my relation"
If someone contacts me and their Tree is open, then I have a quick look at the possible relation and make my judgment from there,always get back with a yea or nay and then it is their choice,because there is always that possibility that there is a link in earlier years.
4586 relations on my Personal Tree, but only 770 on GR. and I certainly do not copy(on GR) all the researches done by other relations, though I will put them as a Source. It boils down to a matter of respect and courtesy as far as I am concerned.

P.S. Rather than a GR contact, I had a recent PM on here and replied with my connection to the family. I did a search on GR and found the same person who had contacted me. Sent a message and opened my Tree. Two days and no response on GR or on Rootschat, so closed the GR link. Not everyone on here is perfect!! At least one can check on here to see if they have logged in, and this gent had, so no excuse for bad manners.
