Chase Dale has been noted to have vandalised three articles at time of writing. They are SCP-2007, SCP-1015 and (in-deletion) SCP-2593.
In SCP-2007's case, they changed the title to "SCP-20017". In SCP-1015's case, they changed the word "penny" to "penis". In SCP-2593's case, they deleted everything from rating module to Special Containment Procedures. I reverted all of them. To my knowledge (and at time of writing), these are the only affected articles.
Suggesting at least revocation, especially if this behaviour persists.
