Sysoprevoke is a user "right" which can only be added or removed by mods. It prevents a user from using any of the tools of sysop, even if they are marked as being a sysop in user rights. In other words, it prevents anyone but a mod from re-sysopping someone. Techs have the technical abilty to sysoprevoke themselves or a user who has self-requested it, but are not permitted to put users in sysoprevoke unilaterally. Techs are not permitted to remove sysoprevoke placed by a moderator without approval from a moderator or the mob.
