Answer #1
Your question is too vague:
do you mean how do they work – technically?
or
do you mean how do they work in am internet or social sense?
it’s as if WBB had a forum section – off topic, lets say, that was open to anyone.. but they charged a membership fee to access helpdesk.

It’s something of a con anyway – all of the info they have is just stuff collected form elsewhere, then they charge for access to it.
It’s for lazy people who can’t be bothered with a proper Google search (with + to ensure a word is counted and – to remove a word from searches)
no better than a survey-to-download website.
Answer #2
Just more crap to avoid, basically!
Answer #3
@…yes i mean technically how does it work…
Answer #4
Probably just a login like here, but here is free to register.
Imagine it like Uploaded – you have to pay the get access to UL premium – and you get access to “answers” instead of hosted files.
(The deeper nitty gritty of HOW a paid-access site works is for a NetTech to answer.. and the full answer is probably quite complex).
Answer #5
when you pay they give you a account and you sign in thats how it works, you keep paying and you can acess their articles, happens all the time when i read news on google news links it gives me links to pay to read news sites like the christian journal.
