Revert r35857, 35858, 35859 for the moment. Some notes:

* Calling $user->isActiveUser() looks a bit redundant. :) Consider either shortening it to isActive() or changing the last word to be clearer, say $user->isActiveEditor()
* $wgActiveUserEditcount <- consider fully casing here; "editcount" isn't a word. :D -> $wgActiveUserEditCount
* $oldTime is dumped into SQL without any escaping or quoting. This will happen to work on MySQL but will fail on PostgreSQL, and is generally a bad practice. Use addQuotes() to ensure the formatted timestamp string is escaped and quoted for your raw SQL construct
* the database result object is not freed, which will leak resources if used in a long-running script
