Well I'm curious what's going on, cause I...:

- ran the query to change the setting to "-1" for all users
- checked up on random users in the admin CP only to see that the setting was still blank for each of them
- ran the query again only to see that no rows were affected (so seemingly all were changed to -1 even though the admin CP... still showed them as blank?)
- logged in using a regular (non-admin, non-mod) account only to post two posts in 15 seconds, bypassing the admin setting of 180
