The fast generation of PoS block is still ongoing, about 55 out of last 60 blocks, and in the amount of 250/500 PPC, so I presume it's the same person.  Is this normal or something that can be safely ignored?  Or in Jutarul's word, this can actually be "good" for PPC, attracting more people (including potential offenders) to generate PoS blocks and thus making the PPC network more secure, and not someone exploiting the vulnerability by hastening the cycle?
