Apparently in germany they caught a pedo like that. Watching certain nodes and the sizes of files that are sent between them to identify the admin of a pedophile image sharing forum. Took them 1 1/2 years to identify the specific person, but they got him.

Considering this I would imagine it's pretty safe for the average user since they have to specifically target you for a long time, however it seems like with enough effort it's possible to identify someone even without Clearnet slip-ups like it was the case with Silkroad.

Once they have your address they will just storm your house and catch you on the computer, then you are done for.
