No way to bulk delete : deactivation / deletion of plugin keeps all data

Hello @shift8

We sincerely apologize for any inconvenience caused. We understand your frustration and appreciate your feedback. In our system, we retain residual data to ensure that users’ existing data can be recovered if they unintentionally delete the plugin and decide to reinstall it later. However, we acknowledge your concerns regarding bulk deletion of redirects and residual data retention in the database.

Rest assured, I’ve taken note of your feedback and will forward it to our development team for further consideration. Thank you for bringing this to our attention.

For future reference, I would recommend?starting using our?BetterLinks – Shorten, Track and Manage any URL?& All the Docs is available?here

In our BetterLinks you can delete all the links with bulk select options with lots of other features

Hope it helps
Thanks

For anyone else curious and slightly more intermediate with MySQL you can just run this query to bulk delete all the redirects from your database. Tested in multiple environments, just be sure you take backups before just in case :

delete from wp_options where option_name = '301_redirects' limit 1;

Its all JSON encoded serialized data in that one row in wp_options.
