can someone give me a little idea about this kind of setup and whether it's a good idea to subscribe to such network to get cheap internet access? will the admin know all the websites i browse? can he block websites? is there away to get around blocked websites? will he know my monthly download traffic? is there a way to protect my privacy? will using TOR (onion routing) work with this kind of setup? thx

Deleted because not related.

And to add to dobby, it's just not mikrotik. ANY network or ISP can have these capabilities and most do.
