- How much can I trust Tor? 5 answers
I ask because I've heard of some online communities that say they have no options but to deal with repeat-offending trolls no matter what, and the site cannot stop them because of Tor/proxies/VPN/etc., and they are deliberating harassing, impeding and otherwise being destructive and toxic to communities.
Is it true that, given some habitual measures of abuse, you can sometimes be truly anonymous?
