Clicking Delete on a WordPress plugin shows a success message. The database tells a different story. Rows survive in the options table, in post meta, sometimes in custom tables, quietly bloating every backup and slowing every migration.
In this video:
- The leftover fingerprint: how much orphan data really accumulates
- What uninstall.php is supposed to do, and why most plugins skip it
- The legitimate engineering reasons plugin authors leave data behind
- An audit recipe using both WP-CLI and raw SQL
- A safe cleanup pattern with a non-negotiable backup step
- The plugins where cleanup is the wrong call
This is not a moral panic about plugin authors. The skipped uninstall hook is often a defensible engineering decision. The goal is to give the developer a calm, repeatable audit routine, not a reason to nuke a production database on a Friday afternoon.
