Introduce a way to also permanently delete the sensitive info from the staff logs

Anyway, the log can be also deleted with rails c like this:

UserHistory.where(post_id: xxx).destroy_all
# or topic:
UserHistory.where(topic_id: xxx).destroy_all

This looks like it will delete all user_histories records associated with the post or topic id, rather than overwrite just the details section or limit the destructive action to only the permanently deleted log?
