Geocities 
Exactly what policy does a site published by Geocities violate?  The article is well and professionally written as well as nicely-presented.  What's unreliable about it?  The fact that it was published on Geocities?  Plenty of good articles are published on Tripod.com or Hispavista.es and they're acceptable?  Why, because the user can invest on a domain name?  Because that's the only difference.
