I’m sorry to tell, but Tor does give you privacy and anonimity, at least a fair amount of it. However, if you don’t care about poor OpSec, you will get caught sooner or later. That is what got Eldo Kim caught. Just give the wrong people the possibility to do some correlation attacks and you will be out.
You can learn more about the case in one of DEFCON’s talk, here.
And yeah, I’m happy he got caught, people shouldn’t use the Tor network to do bad things.
