Take an invite from the troll

The idea is as follows (by example):

I give an invite to a person for an interesting article from the sandbox. Then over time I discover that he did not publish that article, “behaves incorrectly” on Habré, spoils my “good name”. etc. And I already regret that I gave him an invite ...

Can implement the selection function of your invite? Of course start with warnings, etc.
Or create a “complain” function on a user with my invite.
Or a special Karma downgrade immediately to 20 only from the owner of the invite.
Or give him a badge - such and such a user refused.
A bunch of options ...

Habr himself of course "cleans" such people using karma and rating, but this happens rather slowly. And I am just ashamed of him, since I am responsible for the one whom I “tamed”.
