Provider on my Facebook Question

Have had this happen a few times and the only thing I can think of that explains this phenomenon is proximity. It seems FB puts people you get close to in your "people you may know".

You click 'like' on a funny picture. Someone else 'likes' the same picture, or any other picture from the OP, and they are added to the list of friend suggestions.

i have a separate hobby FB account tied to my hobby number just for thie reason. On my RW social media I have my shit locked down like Fort Knox.

Best thing is not to have social media, I don't need ex-anybody's finding my ass lol, I like to creep and cant do that with social media.
