another option is to time-limit the editing/deleting of posts. Kind of makes people take responsibility for what they post. (if they are deleting something which has lead to a ban, or warning or similar)... but doing it to normal posts seems strange.
no ideas what triggered this then? it is a shame to see anyone leave in such a manner.
