Please sign and share the petition 'Tighten regulation on taking, making and faking explicit images' at Change.org initiated by Helen Mort to the w:Law Commission (England and Wales) to properly update UK laws against synthetic filth. Only name and email required to support, no nationality requirement. See Current and possible laws and their application @ #SSF! wiki for more info on the struggle for laws to protect humans.
Noise vs. Signal
Identity disputes must be avoided as far as possible. This could be maybe done by sharing user-table between the databases. Thus registering in one Wiki would automatically create an account in the other. When disputes arise the needs of Signal Wiki overrides those of Noise Wiki
This does not resolve how Usernames taken elsewhere could not provide confusion by someone hostile registering as themselves as User:Jimbo Wales or User:Fred Bauer for example to make trouble. Though these would naturally be moved by sysops to their traditional owners.
What problems does this present?
