    Why does everyone think the only downside to Tor is "it's slow"? Are malicious exit nodes that hard to explain?https://twitter.com/njkobie/status/848474637700931585 …

        Chances are: 1) you don't need Tor 2) you don't understand the risks of using it 3) you're better off with a VPN, like @AlgoVPN

        False "everyone" there to start. On point: malicious servers like adtech and rogue nodes, both, are standard part of net

        You take on more risk, not less, by reducing the barrier to entry for others to eavesdrop your traffic by routing it all through volunteers

        The Tor Network attracts malfeasance due to the ease of manipulating data in it and propensity of criminal use cases.

        You're way safer on public internet with HTTPS Everywhere, an ad blocker, and a properly sandboxed browser.

        @DonAndrewBailey @njkobie @TeenVogue @SarahJamieLewis @JoeBeOne they said use tls which should protect you from exit nodes

        It only requires a single auth attempt / single unencrypted packet to fall victim. IMHO "Use TLS" is useless advice in this circumstance.

        I guess it matters if you think the PLA is running the nodes or just some bros

        It's pretty easy for just some bros to run ettercap and sniff passwords forever.

        It's not an all or nothing thing anyway. Tor has value but only with expertise; Algo is well suited for more practical use. Different scopes

        There are no bad exit nodes, just alternative exit nodes!

        "vaguely similar"? As in ISPs will also actively capture unencrypted credentials and sessions for sale/exploitation? ;-)

        The main problem with Tor is neither speed, nor malicious exit nodes. It is CloudFlare. Makes some 10% of the clearnet sites unusable.

        right, because nothing malicious has ever come out of Tor.

        It's hard for anything malicious to come through, when you can't even access the goddamned site due to CloudFlare...

        I guess you've never tried one of these 10% sites, then. You get endless CAPTCHAs that don't even work properly.

        Sometimes they can be avoided by turning JS on - but that, of course, is insecure.
