Hey there, as a member of the community you are free to voice opinions in a constructive manner, however leaving a demotion thread on a staff member's message wall is not the best way to approach it. If SemanticDrifter has emails activated he'll receive an email for each response to your message, and can be a serious distraction. Items like this should really be raised on the community in question, and sent to staff through Special:Contact so they can assign the situation to a staff member best suited to dealing with the issue. If the forum keeps getting deleted be sure to place the user's deletion log in the report as that'll help further your evidence against the individual. However, it's also worth noting the recent Wikia blog by Master Ceadeus 27 which notes that features such as the chat or IRC cannot be used as evidence against a user due to ease of manipulation of data.
