One possibility is that they have their user preferences set to
automatically subscribe to forums when they post. If they click on their
name and go to *preferences > user*.
On that page under *User account* there should be an option for *Forum
On the *Forum preferences* page there is a *Forum auto-subscribe* option.
This is likely currently set to Yes. If that is the case, it sounds like
they want this changed to No.
