Re: section on "Immediate action: Blocking users"
I realize the current practice is to block or ban users who are harassed - I cannot name any user who has spoken out against harassment who is still in good standing and actively editing - but I do not believe users who are being harassed should be blocked.
Also I do believe the section "Removal of non-public personal information" needs to be given the highest priority. PII should be reverted immediately to make suppression easier, and users should be informed of how to get PII removed.
Your section "Handling personal information: Responding to posters of PII" has a confusing statement that "deliberate PII release" ... "could also include leaking personal emails or other communication which could be compromising". It is not clear if this includes correspondence that is in violation of policy. For example, if someone sends you a harassing email or obtains your email address then attempts a DDoS attack on you, according to this policy you cannot reveal these attacks, which most people would regard as harassment; if you did you would be vulnerable to immediate and harsh retaliatory admin action that could not be appealed.
