Maybe it would be helpful if the admins (and mods, as I have seen different mods handle such things differently, too) here had a common approach to this issue. As it is some "officials" say it's a total no-no, some handle it case-by-case, and some are pretty much for it.
Since you're the head-honcho here I guess what you said here is the "law", but not every mod/admin seem to enforce it.
