We have a client site that has been getting a lot of spam registrations. We're turning on purgePendingUsersDuration
to help deal with some of these automatically, but I was planning to go into the database to delete a bunch in bulk directly (since there are almost 200 of them)
Is it safe to delete them just from craft_users
and craft_usergroups_users
tables? Are there other places I should watch out for?
