Can the Borg tell what sites I've been to?
The obvious question here is being overlooked..........
Why are you going to that garbage website in the first place?
Maksutov is correct: they can only see which website you came from, and only if you appeared on their website by clicking a link.
They can't see wherever you fo after you visit them, nor where you came from if you just type in their url in the address bar.
Cookies cannot be shared between website (unless the websites work together on that, which seems very unlikely since WT doesn't work together with anyone but lawyers)
If I was a JW or cared I would be worried too. The internet is a weird black box machine that I have no idea how it works, but I do know that if I go on Amazon and search for Shaun the sheep movie dvd's and then go onto Facebook, the adverts are Shaun the sheep related. So you are carrying some kind of data "stink" around with you when you travel the internet. I believe that deleting cookies or private browsing stops this happening. It's internet deodorant...
Nowadays, I've gotten in the habit of opening a new tab or browser for each site. It's cumbersome but I value the little bit of privacy I still have left.
To be technical: websites that (appear) to know what you looked at or searched for earlier, are collaborating.
When you search on Google/Amazon/whatever, this website stores information on that and/or share it with advertising companies.
Then when you visit some other site, the advertising company displays ads they think are relevant for you.
Not the key word here: collaboration.
Without collaborating, all a website can know is what you do on their website(s). They can't see what you did or do on other websites.
The only thing they can see is where you came from if you arrived by clicking a link (not if you type in the address yourself).
Now do you think JW are of the collaborating kind....?
Purrpurr, the best way to answer your question is to say, “You’ve been a very, very naughty boy.” Now close that lap top, clean yourself up and use your bed for sleeping. Good night.
If you really want to have fun go on JWFacts on their wifi in the Kingdom Hall.
