How to Ignore all threads started by an Ignored Person?

How can I Ignore all threads which have been started (or more relevantly, are being started) by an individual I might have chosen to Ignore on the grounds of a history of starting annoying and stupid threads?

is it even possible with this BBS software?

A certain other Atlas forum has of late acquired a density of posts by one individual, and I would rather not see those posts...

Not sure this is possible ... I'll forward it on to our webmaster, though, and see if she can find an add-on or something to do it.
