Your first paragraph was my original response. But I read past the first 3 sentences and realized that this is a valid cause. The bad coins should be attacked. This is noble work. It's not done out of malice or a general hatred, but to cull the herd or at least toughen the coins that remain standing after the attacks.
Hopefully the OP will share his findings and we will learn more about PoS crypto. I'm very interested in the results.
Perhaps you read something that I missed then. In his OP he states his reasoning is because of the "quantity" of coins, not the "quality." Personally I see no reason to attack coins, especially ones that meet his own agenda and not the consensus of the entire crypto community. History has shown that most all shit coins will die natural deaths anyway. Let the herd cull itself instead of having some wannabe savior of the crypto world launch attacks on whatever coins he chooses.
