I see negative comments on this on here and (mostly) reddit.

But the reality is this is simple and yet brilliant approach to stop misinformation and policy violators. May be even lazy approach to avoid doing the hard work. What does any policy offenders usually do? Create new accounts and post the same misinformation slightly modified.

Between Youtube and PlayStore, google has seen enough of this trends. I am surprised it even took them this long to limit virality of new accounts.
