Do they know that you’re accessing tor? for example if you are the only one in the building sending requests through it, can they pinpoint?
Discussion
I think so, unless you use a vpn
This^
I would run Tor over VPN. That way your ISP doesn’t know you’re using Tor, and the Tour entry/guard node doesn’t know your real IP
Best combo I’ve grasped so far
Does your ISP know you're using a VPN though?
I believe so, but this typically less of a risk, because there are various reasons to use VPN. (Whereas Tor is still associated with illicit activity).
But you make a good point - what if VPN is illegal in your jurisdiction?
I believe Tor “bridges” and/or “snowflakes” help with this problem. But it’s beyond my understanding at the moment
