Save user page to file when deleting account

[Ryan J Ollos]

There was one unfortunate case in which I deleted a valid user account while doing spam cleanup. I discovered this a few days later when reviewing the "Account deleted" notifications that AccountManagerPlugin is configured to send. It was just luck that I recognized the username, otherwise this would have gone undetected for at least a while longer, and for all I know there could have been other valid accounts accidentally deleted. The user that I deleted is matobaa, and the page was restored from the "way back archive". I suspect that I intended to delete the user immediately before or after this user in the table, and just wasn't being careful enough.

As an additional safeguard, it could be useful to save the user's page to a file when deleting accounts. Alternatively, or additionally, we could avoid deleting the user's page or warn when the page has more than 1 version (see related [14261]).

I think it's probably better to focus attention on implementing ​trac:#9222.

It looks like user jeangui was also deleted (accidentally?). Previously jeangui was creator of the DefaultCcPlugin and LatexMacro. See log:defaultccplugin?rev=5293 and wiki:jeangui?.
