Run the following query from labs
```
select user_name, up_value from user_properties inner join user on up_user = user_id where up_property = 'timecorrection' and up_value != '' limit 30;
```
Gives a list of users and their timezone. This seems like a privacy breach as timezone is strongly correlated with location. You don't even have to do the correlation yourself. Consider the following query.
```
select user_name, up_value from user_properties inner join user on up_user = user_id where up_property = 'timecorrection' and up_value like '%America/Los_Angeles%' limit 30;
```
Now you know a bunch of users who live in California.
I think this preference should be considered private and redacted from the tool labs db.
