User blog:DrObscure420/"Open Source" Characters

I am curious what the policy is regarding "Open Source" characters? For all intents and purposes, most lead to dead sites. For all Open Source characters i have witnessed,they never featured in an actual comic. If this site is meant to preserve history and public domain characters, why are there over 500 "Open Source" characters permitted alongside actual history? Can these "characters" be moved elsewhere, or is there a way to filter them out? There's like 20 Jenny Somethings for one unused character.
