There is this provider I’ve been seeing 3-4 times a year going back nearly five years.  Older (50+), married.   Open marriage she always told me and her activities are very low-key and OTR.  We occasionally exchange e-mails in-between get togethers.  Lives about 75 miles away.  Great gal, very comfortable relationship and one of my ATF’s.

She obviously told the husband about you.  Maybe they are into 3 somes!

It will dig names out of your email.  It will pop up ads for products based on your viewing cookies.

If she or he has searched for your name on Facebook, this could happen. But, only from the account that searched for you.  He likely knows your name or has searched for you. He probably has seen her client names and searched for you on Facebook

ould be several things or combination of factors.

That was my best guess too.  Had to be from his account ...

Her phone number might be attached to her Facebook, or email.. Which you might have on your contacts.

You connect with her via email, on the internet.

and clear cashe & cookies...  before hobby stuff.  And between shopping.  I use to have shopping searches...  which I decided NOT to purchase...  then pop up as ads on FB or Yahoo mail.   Really Piss Me off.  
One can not be too careful.

I am rather outspoken about the dangers of social media.  Search the General Board for "nefarious, plague, insidious, pernicious" [Any of these words] for the past couple of years and you are sure to find my posts.  
 
Those threads, AND NOW THIS ONE, have examples of the unexpected and undesired cross over of this world and the real world.  
 
The stated goal of social media is to connect everyone everywhere, WHETHER THEY WANT TO BE CONNECTED OR NOT

if I have a phne which I use for my hobby contacts, but I have my laptop which I use for the hobby sites, which one should I have facebook on to be safest? because.... I need to keep hobby from real life as away as possible.... I don't know if my question makes sense lol.

That's good! Makes me mad too, no business taking my searches and then serving me ads.
That's why these sites are "free". They are not free at all, they take all our info and sell it to make BIG bucks.

It has happened to me as well.  Facebook links your contacts from your phone and makes suggestions on ppl you may know.  He may or may not see you but it shouldn't matter as long as you don't request either to be friends. Best way to not have this happen is to use a alternate number not linked to your phone number.  I suggest you alter your personal settings as well.  I have mine to where only friends can see my posts and  friends of friends can request to be friends.

My solution:  Stay off social media altogether is at all possible

One day a massage provider showed up in the same manner, and it had been a couple of years since I had seen her. I did a double take and sure enough it was her.   Now I have to wonder if I showed up on her "people you know." I'm guessing it did.

I've had several people I've searched on other social media accounts before call me out on searching them. I.E. LinkedIn etc... I'm no denying that the contact list don't play a part but IMHO and experience it's a search thing. I know I wouldn't look at anyone's profile if I didn't want them to know I was.

Lol they are not the same, but happily take the treasure trove of data they gather for free from us 😜

Remember when Z. was bought out and given a MO bride?

I am constantly asked if I know someone who is in my contact database that I haven't communicated with since before I joined FaceBook.  There is no other way they could have put the 2 of us together.
