What would stop a bad actor from creating a bunch of new circuits and

yes there are distribution strategies that can prevent that
or make that very expensive (an /48 IPv6 block has a **lot** of IP addresses)
Sure, but wouldn't sites start blocking at /48, /64, etc levels?
the feature is primarily targeted towards reputation systems that look at the
specific IP address only. Maybe some will move to prefix based reputation but
the assumption is that not all will.
This is all very interesting. I read several of the links (bugs & some
non-tor-talk forum questions on this general subject.
I've now had more time + paying more attention to my procedures &
typical results on youtube.
I can't explain what I'm seeing, since apparently in theory (unless it's
outdated info), getting a new identity should be equivalent to closing /
By now, it's seems safe to say that if I've visited any other sites
*before* loading YT in a new tab, the chance of YT *NOT* giving the
"suspicious activity" warning, is very low.
** Which begs the question, why would cached data from other sites
affect whether YT thinks the new exit shows suspicious behavior?
I DID discover just now, that the pref in my user.js file,
user_pref("browser.cache.disk.enable", false); - was NOT observed. In
about:config, browser.cache.disk.enable was True - bigger than Dallas.
Further, when I toggled it to False, that is the default setting. I
can't 'splain why it wasn't using the user.js value. It worked for yrs.
I've never seen it happen in any other browser.
In a VERY short trial just now (statistically meaningless), after
changing "browser.cache.disk.enable" = false, I still usually needed a
new identity for YT to load. I don't know what a new identity oc
clearing cache has to do with a site not visited since launching TBB
But a new identity WITHOUT clearing the cache rarely worked on YT. Can't
say the same about other sites. I tried it enough times over weeks, to
see clearing cache AND a new identity almost always worked. Question is
Just luck of getting bad exits when cache wasn't cleared before a new
identity, or getting VERY lucky - with "good" exits when cache WAS
cleared is statistically improbable.
