Is taking steps to stay anonymous online ultimately futile?

Last time I checked, Mullvad let you create an account completely anonymously and pay in cash through the mail, either euros or USD.

Last time I checked you could walk into a store even and pay with bitcoin or cash with Mullvad. I liked thier ToS as well.

you have to buy bandwidth from a bigger provider who can spy on all the bandwidth they sell to you..

They still know your ip though.

can you use free proxy server
will it work? better than vpn paying

you can use a 3G USB modem with prepaid sim cards
you can use your neighbors' wifi

You are overthinking this. It's very easy to get lost in the woods with this shit and feel like its hopeless. The trick to staying anonymous is having multiple layers of security, here's an example:
CIAniggers are going to have a hard time trying to fuck with all that, let alone anyone else.

Even then it's next to impossible with Tor. Basically if you call in a bomb threat SIP over Tor on your university network and you're the only one who ever used Tor at that time you become a prime suspect, but without proof and without your admission it wouldn't (shouldn't) be convict-able.

They know that you're connecting with Tor but nothing else. Just use it for everything. Recommend it to people.
Tor anonymises packets so it isn't possible to guess what you would be downloading that easily. Regarding connection times - trivial to fake.

Don't bother with (((anonymity VPNs))) unless torrents are illegal in your country.

Regarding adblocking - it might deanonimise you as well. The best way is to use Tor Browser with default settings - it makes every Tor Browser appear to be the same.

Why?
