if I find a name of someone I think I know, if I go on their site do they know I've visited? I know nothing about fb....
I don't know much about it either capt. but I'm sure they don't. I've never known anybody 'look on my page' 
What's the harm in reading other people's feedback or what Items they've sold or still have up for sale? If there's a watcher or a bidder on one of my items, I'll automatically go into his feedback to see how he/she presents his items. Do we have a similar style in selling, and how do our prices compare? There's nothing clandestine about that. It's only by comparing oneself to others, that improvements can be made. I try to fill in as much detail as possible about puzzles so as to make them interesting, going as far as Googling a castle, for instance, to find out more about it, whereas my "rival" doesn't and puts most of his up for 99p so if there are no bids, he loses nothing. I won't do that because I sell quality puzzles like Ravensburger, Falcon and a few others, and I don't reckon on letting those go for £1.20 a throw. He, on the other hand takes several quality close-up photos of clothes he sells and seems to be doing alright that side whereas I only tend to take one. Perhaps I could learn something from him. I'm proud of my feedback, and have no qualms about anybody reading them.
The other thing I do is go into my B/B list to see if they've given bad service to anybody else, and if so contact this grieved person who'd left bad feedback to tell him he's not the only one and to add that person's name to his own B/B list and become somebody's personal Flying Dutchman - Hell hath no fury like an eBayer whose been messed about or worse still been left negative feedback unjustified. I tore into somebody who'd given me bad service. He replied with one letter - a capital "V" in maximum font. I thought: "Yes - we understand each other perfectly."

I never suggested there was any harm at all. It was an answer to a specific question about how FB works.
I was giving examples of how it is not possible to know who has been looking at - for example - your feedback or profile pages on eBay.
It is possible to see, in some cases, for example, which IP address has visited your own website or some chat room websites allow that, but that doesn't mean you will know who it is, unless you can connect it with a definite device.
Silly me! I took FB to mean FEEDBACK, not FACEBOOK.
You must have wondered what the hell I was going on about, because on feedback you can open up a privicy log wherre only you and the buyer know what transaction has taken place.
I'll have to sit on the side and read the threads as opposed to answering them in future. I feel such an **bleep** for getting it wrong - you must think me a right dummy!
