 * Can you provide a way to clear the database? the blc tables have reached 6MB 
   in size and I’d like to clear them out for the purpose of optimizing the db and
   keeping smaller backups. I only enable and use this plugin once every 6 months.

 * Hello [@squeebo](https://wordpress.org/support/users/squeebo/)
 * Not sure what you mean by clearing the database, if you want to wipe out relevant
   records/tables then you should look for:
 * 1. a **blc_installation_log **record in the **{db_prefix}_options** table
 * 2. the following tables:
    **wp_blc_filters wp_blc_instances wp_blc_links wp_blc_synch
 * Warm regards,
    Dimitris

 * Would that wipe out the plugin settings and/or break the plugin? I just want 
   to wipe out the broken link records that are taking up so much space, since they
   aren’t needed and I’ll just have it regenerate the list in a few months when 
   I use it again.

 * Hello [@squeebo](https://wordpress.org/support/users/squeebo/) ,
 * Those tables are not holding the options for the plugin, so when you remove records
   from them plugin will still have options.
    Before removing any data from the 
   DB you should have a backup of DB, just in case something goes wrong.
 * kind regards,
    Kasia
