This is a hidden comment, to be placed at the bottom of external links sections where there is a pattern of advertising being added, without useful info.
This must be added in this way:
As of 23 Sep 2012, the comment is as follows: <!-- NOTE: PLEASE DO NOT ADD LINKS UNLESS THEY CONTAIN USEFUL INFORMATION. Commercial links will be promptly deleted *UNLESS* they contain useful information about the subject. -->
If the "subst" is ignored, the hidden comment won't be visible to someone editing the section.
Alternatively, just type it in. This template is just meant to be easier to remember, rather than working out something each time which is consistent with our policies, and not too unfriendly.
