Ok so every1 is complaining about new coins, put your hasher where your mouth is, simply set up a pool, have miners point to it, and by some sort of vote, decide which of the crapcoins to 51% attack, it would kill them before they start and crapcoin makers wouldnt release them if they know they wll be 51% attacked
you sir are an idiot and do not understand what a 51% attack is supposed to do. 51% attacking a coin that is not even exchanged doesn't matter for squat and the market value for these coins is paltry. All you will do is slow transactions down for people and all the while your band of misfits has redirected hashing power that could have been spent mining more reputable currencies.
You won't stop the flood of new cryptocurrencies. Best thing to do is ignore then and they will go away.
