Before proposing or commenting on new or expanded criteria note that CSD criteria require careful wording, and in particular, need to be all of:

1. Objective: Most reasonable people should be able to agree whether a page meets the criterion.
2. Uncontestable: Almost all pages that could be deleted using the criterion, should be deleted, according to consensus.
3. Frequent: If a situation arises only rarely, it is usually easier, simpler, and fairer to delete it at the normal venue.
4. Nonredundant: If the deletion can be accomplished using a reasonable interpretation of an existing criterion, just use that.

Note this is a summary of the requirements; see Wikipedia talk:Criteria for speedy deletion/Header for details.
