I've actually posted somewhere a long while back that I'd pay a bounty to see someone break our anon feature.  I'd pitch in $1000.00USD as part of my own funds towards the bounty if someone can break our anon tech.  I might be persuaded to actually put more in if a few others want to pitch in.  

Until someone proves that they can break it.....its solid! FYI...that challenge has been out for over a year and nothing.
