I understand you concern about shit coins. But creating this coin will make you as guilty as them. I have a suggestion, not that i care.
Create the 100% premine coins and 100% POS coins. "If you can't beat them join them." Offer the developers of the shit coin a stake of your 100% premine/POS coin if they let their coin die. Or maybe buy all their coin and throw them away. Combining all the shit coins may create a value somehow, you may call it Fertilizer coin xD
Thx for your concern. But we will do that the hard way.
