The facts 

For anyone that has further trouble with troublemakers as I have, consider the following from the wikipedia rules (such as http://en.wikipedia.org/wiki/Wikipedia:Vandalism) in your rebuttal (or just ignore them!):

Making bold edits:
    Wikipedians often make sweeping changes to pages in order to improve them - most of us aim to be bold when updating articles. While having large chunks of text you've written removed or substantially rewritten can be frustrating, simply making edits that noticeably alter the text or content of a pages should not be immediately labeled vandalism.

Talk page vandalism
    Removing the comments of other users from talk pages other than your own, aside from removing internal spam, vandalism, etc. is generally considered vandalism. Removing personal attacks is often considered legitimate, and it is considered acceptable to archive an overly long talk page by creating an archive page and moving the text from the main talk page there. The above rules do not apply to a user's own talk page, where this policy does not itself prohibit the removal and archival of comments at the user's discretion. Please note, though, that removing warnings from one's own talk page is often frowned upon.
