  Where does the extortion part come into play?  I see a small possiblity for such a thing to be used as extortion but that does not seem to be the purpose here. They would need to withhold the information and then contact the person first to 'threaten' to release it. Verses just putting it out there automaticly. I mean, someone paying to get their info removed after the fact is already too late thanks to the nature of the internet.

  It is certainly possible for it to be done with Bitcoin. But, how useful would seeing; IP-195.168.1.555(yes I know it's not valid...) bought coffee, some socks, sent a few random IP's BTC and sent some BTC to MtGox really be? I think the main thing to take away here is that both torrent and BTC reports would only work on users who did not know how to anonymize themselves properly. Anyone who cares enough to not have their internet usage tracked should be making that their first step.

  aye, and those people should know how to be anonymous. My inclusion of 'a few random IPs' was meant to include people that are sending/receiving to places unknown. And was not a list of what I use it for. Though I have no desire to use it for anything illegal, I can certainly appreciate someone's desire to not have their purchases known. I happen to service some of those entities now with USD.

But, that doesn't really answer your question. It's been said many, many times though that bitcoin by itself is not completely anonymous. Yes, it would be possible for someone to aggregate all the IP information associated with transactions.

Yeah, good my IP is shared with ~1000 other guys, IP6 will be a real privacy bust, but by then I guess everybody will use tor

"Hi. We have no records on you."

me 1up.

Agreed.

Let's make it so simple for people it's stupid not to use it. 

Yep! They have my one and only transaction on record. For the record, I bought that chicken for a Christmas present, and not for personal satisfaction, of which was very upsetting for the chicken, for I think it liked me.

Thank you for bringing this to our attention. I will now on make doubly sure that I mask my IP (Individual Pleasure) for my next purchase.

Congrats on the 2^11th post!

Admin of that forum (yes ok and of every website we ever surfed) can know what we downloaded

Bitcoin transaction doesn't have the IP address of a sender, because bitcoin protocol doesn't rely on it. The only way for some one to find out IP of the sender is to receive transaction broadcasted message directly from sender, use of any kind of proxy will deny that see: What is BlitCoin?

By the way, maintainers of www.youhavedownloaded.com (http://www.youhavedownloaded.com/) said that they what to create anonymous file sharing protocol based on bitcoin technology:
