I think the bitcoin community needs an open source instrument for attacking emerging block chains. I mean, several people would happily lend their hashpower to attack these junkcoins but there is no instrument for them to do so.

Seriously, someone needs to develop an attacking tool to be used as the base for attacks ... Sure, it won't be universal since emerging blockchains may protect against it, but that's why it should be open source - to be able to modify it easily to be used against certain new shitcoin.

This won't be dangerous for the bitcoin since there is no such hashrate to attack it, but new chains would be vulnerable.
