My guess, VAC provides a way of blacklisting manually, in addition to any automated blacklisting it has.
Jag was using an advantage not available to most players, and not provided by the server admin/op. That's not acceptable to me, but I would not be surprised if people run servers were anything goes.
And there is no indication in the other thread as to whether this activity was sanctioned on the server he was playing.
In any case, he deserves to be banned for having such a horrible avatar (that might be in copyright violation), IMHO

.
How appropriate is it for a server admin to use server plugins to have an advantage? At some point you have to recognize that people can choose which server they play on, and if someone is a jerk on one host, you are free to find another server.
