Moderation:Policy Discussion/Signatures

Reason
Throughout my time on Wikis I have noticed that the template signatures have the potential to be used for vandalism and there have never been any clear guidelines to stop people from changing these into something destructive. As you know edits to your own user page cannot be considered vandalism unless you impersonate someone. However an edit to a signature can be much more destructive to a wiki then any amount of attempted vandalism may be. This is because 1, User pages are protected so the signature cannot be edited by anyone else, and 2, because if the user has signed allot of pages then it'ld be very hard, if not impossible to eliminate all of the users vandalism due to the fact that hundreds of people would have made edits over the users edits. This policy aims to allow moderators to revert this form of vandalism.

What wouldn't be allowed

 * Signatures which have malicious or inappropriate links, for example a signature which contains a link to the logout page.
 * Signatures which have images higher then 14 pixels high.
 * Signatures which generally break the wiki in some way either through formatting or other means.
 * Signatures which impersonate another user.
 * Signatures which have inappropriate or offensive images.
 * Signatures which contain curse words.
 * Signatures which link to PHP scripts and other such technologies.
 * Signatures which contain images larger then 50kb

What would be allowed

 * Anything that doesn't come under what isn't allowed.

Punishment
If a signature doesn't meet the above requirements then these steps will be taken.
 * The user of the signature will be warned once and asked to change it. The user has one week to comply.
 * If the user does not change the signature then a vandalism case will be brought fourth where the user may receive a warning or banning in accordance to the vandalism page. The user has three days to comply extending out till when they next sign, if they continue to sign with said signature then they will be placed forwards for another vandalism case.
 * If a user repeats such actions then the initial warning can be skipped and the vandalism case can be brought fourth immediately.

In the case of a template style signature a moderator may revert it back to its last proper functioning form. If a signature is changed so it breaks the wiki as to render it useless the user who alters it shall be perma-banned with no questions asked.
