A quick adaptation of the theme restriction code for plugins. Can only restrict on a site-wide basis, though it will only affect those sites on which it’s activated. Does not restrict super admins. Plugins must be active on the main site to be controlled by this plugin (this is an issue with WordPress’ plugin structure).

Restrict Multisite Plugins

Allows network admins to restrict which plugins are available on sites, similar to themes.

GamiPress – Block Users let’s you block users and roles from getting awarded through the <a href="https://wordpress.org/plugins/gamipress/" title="GamiPress" rel="ugc">GamiPress</a> awards engine!
In addition, blocked users activity won’t be registered on logs what makes it ideal for stop registering and awarding undesired user roles like site administrators.
