So the choice then would be whether to give the potential sockpuppet the benefit of the doubt and allow treatment of them to asymptotically approach the treatment of known Dmytry accounts to the extent that and for as long as they make Dmytry-like posts and for as long as it looks like the comments could be anomalies. ie. There is the expectation of either a regression to the mean or that an actual new user will be capable of learning from feedback.

If it is assumed that the accounts are sockpuppets then they immediately get treated without the benefit of doubt and with the additional loading penalty given to sockpuppets for being sockpuppets.
