How many sockpuppets have checkusers quietly blocked and left the sockpuppeteer to edit on without the community's knowledge? At least one too many for my tastes. I'm privileged enough to know who the main account is, but not privileged enough to share this info with you, the community. Unfortunately I cannot say that the main account has learned anything at all from this situation except that he has friends in high places. So, so long, farewell, and demand integrity from your checkusers.
Sunlight is the best disinfectant.
