Does FB Automatically Block Specific Profile Due to Repeated Views?

I'm not sure, because they might not disclose their exact policies on it (and I'm not gonna bother anyone at FB to ask about it) but I did want to point out that one possibility is that she started showing up as a suggested friend and then was blocked, or that somehow some of her activity was noticed (misclicked like on old photo etc).

Thanks Robert... I appreciate your taking the time to post a reply. Blue indicates that she hasn't blocked Red, or Red's friend and I believe her. She's an old friend with whom I have never had a romantic involvement and she has no reason to be dishonest. I realize that I might be asking a lot, but if you have a contact at FB that might be able to shed any light on this, reaching out to them would be sincerely appreciated. I don't want to seem dramatic, but this is a matter of the heart, and one which has the potential to impact the rest of my life. The fact is, I love Red and to lose her over something like this would be a senseless tragedy. Please, if you know someone who might be able to help, please consider asking... I would be truly grateful.

Sorry but people who work at FB (or any such site) get bombarded by questions about the companies they work for and eventually grow to dislike the barrage so I'm not going to bother any of my acquaintances about it, they also likely don't even know (it's a big company and most of the time they won't know much more than the public except about what they work on) so it is almost always a waste of time unless it is a question about what they work on (I don't know anyone who works in this area of FB). You are going to have as much luck asking them yourself as I will likely have (either through their contact mediums or by finding random people employed by FB and asking them) because we both have about as equal a chance of reaching someone who knows definitively how this works.

You can also find this out empirically yourself just by asking the involved parties to actually show you their accounts etc and you can see for yourself it it's true so if you really wanna bother anyone about this it should be the folks in this drama in the first place!

Thanks in any case... I appreciate your time.
