@quid, the user I've question mods about not yet being suspended for behavior on math.se has been suspended on at least four other sites. I have not see "network wide", but I think mods here should reconsider how far they let who on at least five SE sites, repeats the same aggressive and hostile behavior.
@MattSamuel a motivation for doing that could be that there is a limit of one year on the duration of standard suspension that does not seem to apply to network wide suspension. (I do not know if staff could cast a regular suspension and override the standard duration.)
