You have to be careful though! A good while ago there was someone posting on Rootschat in regard to a member of my family! Thinking this person was a relative, I gave her A LOT of my info, including some family photos and certificates !
It turned out, from a pm, that Unfortunately, or more probably fortunately, I learned this person was actually a professional researcher!! Too late for me, I'd already given it to her - freely and happily! Preying on the kindness and integrity of genuine RC members, while this relative of mine would have been forking out money to her, left right and centre! I had previously requested that she send me her client's (my relative's name and email address), so I could send her more info directly! No response the first time, but after another couple of tries, eventually she sent me the name and email address! I nearly fell off my chair when she said in the email that "by the way" she was a Professional Researcher. I sent a quick email to my relative, and told her about it, and recommended her to urgently drop the charlatan, and send any more family enquiries, either to me, or become a member on RC where she would never be asked for research payment, but would be given the best level of assistance and more, from clever, honest people, whose aim is to help and assist people, and not rob them blind. I still get angry about it.... so yes, please be sure that you are dealing with a genuine accredited and registered researcher, if you're thinking about going down that pathway!
So, YES, we certainly do have to be on the alert!!
