ModEnc:Policy
Revision Spam
A maximum of three revisions in close succession by the same user will be allowed. A fourth and fifth might be tolerated if they include valuable information. If they don't, or if you move on to a sixth revision, you will be subject to a three day ban for revision spam. This is necessary due to the fact that each hit on the "Save page" button saves a page in the database, using up space, and saves a revision in the history, burying the "real" revisions under dozens of useless edits.
That, and the fact that we propagated the existence of the preview-button often enough by now.
Spam-revision will not be marked as patrolled, so other users become aware of their doubtful nature.
Unexplained Removal of Information
While we do appreciate you revising a page, there is no way for us to determine whether you're vandalizing or "contributing" to a page by removing information unless you provide an explanatory editing summary. Therefore, omitting the summary and leaving us guessing why content was removed will probably lead to a rollback of your revision.
Anonymous Editing of "Maintained" Pages
Make sure you are logged in when editing pages about projects who are maintained by the projects' admins; an anonymous "update" of RockPatch:Status, for example, while we know pd has an account here and uses it to maintain that page, looks more like a mischievous attempt to spread rumors and pressure pd than a genuine report on progress. Such edits will usually not be patrolled, so users are aware of their suspiciousness, and, should the maintainer revert them later, will result in a ban.
