About Activity data - How to get rid of it completely, if you really want
Since this topic seem to come out regularly, I decided to share a "brute force" idea. If you would really like to get rid of Activity logging completely, i.e. no activity logged whatsoever, without touching the Core code, simply change the engine for
Gdn_Activity table to
BLACKHOLE. Table will still exist, but nothing will be saved to it (existing data will be deleted). Every
SELECT will return zero rows, and every DM statement will do nothing.
Important: I didn't test this method extensively, use it at your risk.
