Vandalizing pages means editing a page in a way that defeats the original purpose of the page. Deleting all the text on a page, changing the information to be inaccurate intentionally, etc., these all count as vandalism
Spamming means to deliberatly post a link to another site for advertising purposes or just to get people to click it for views. Doing this anywhere, including your own talk page counts as spam.
Rollbacks are intended for reverting vandalism done by others. NOTHING ELSE. Any abuse of the rollback system, such as reverting productive changes, is prohibited.
This is not a major infraction, but it is still one. It makes it far more difficult to see who exactly is posting, and to contact them if necessary.
You do not need permission to edit a public page on this wiki. As long as the edit contributes to the wiki, it is acceptable.
Talk pages exist for a reason, it is to keep all non-page related info off the page itself. Always put comments or notifications about things on the talk page.
There is no rule against creating pages on this wiki. You are free to create as many pages as you like, as long as they are related to the topic of the wiki, which is the Voltz mod pack.
