It's possible in some cases that people are using admin access authority to do things like mess with people deliberately for the same reason a dog licks its own organs of excretion sometimes - because they can.  I have to believe at least some percentage of deliberate disruptions would be done by individuals rather than as policy or collective collusion. Companies who found something like that would likely not admit it - unless law enforcement or subpoena forced them - they'd simply lie about it to people like us, rather than take a PR hit.
