I agree that this is complete bullshit and a very, very bad idea. This script is now major news on popular German blogger Fefe's page. It is effectively destroying Bitcoin's reputation. Take it down!

Bitcoin is based on the idea that mining is done by users that WANT to mine. *Forcing* other users to mine for you is absolutely awful. Also note that popular browsers like Google Chrome don't even have a JS blocker and once this script is embedded into the other website code, nobody will be able to prevent the miner from running when they want to just normally use the website.
I already see mobile phone companies getting problems because you wasted the user's battery life!

Did anyone figure out the IP adress of the pools used? The only idea I have for preventing this is to prevent the JS miner from connecting with the pool it's mining in. We need a list of pools so that we can block them via an entry in our hosts. This is the only way to stop this effectively, I suppose.

1bitc0inplz, you just made yourself the enemy of the Bitcoin movement.
