[support] Removing content type from taxonomy listings

[Neil Coghlan]

I have a content type where users select a taxonomy term. However, I 
don't want that content type appearing for the taxonomy listings on 
pages like /taxonomy/term/123.

Is there a simple way to do this? The "published to front page" option 
doesn't seem to affect taxonomy listings. I could play around with URL 
based php conditionals in the content template but I don't really want 
to start going down that road.

Regards

Neil
