The simple way is to run the uninstaller steps and then the installer steps.I want simply start from beginning, as if I would installed the addon new.
Code:
php cmd.php xf-addon:uninstall-step SV/SignupAbuseBlocking 1
php cmd.php xf-addon:uninstall-step SV/SignupAbuseBlocking 2
php cmd.php xf-addon:uninstall-step SV/SignupAbuseBlocking 3
php cmd.php xf-addon:install-step SV/SignupAbuseBlocking 1
php cmd.php xf-addon:install-step SV/SignupAbuseBlocking 2
php cmd.php xf-addon:install-step SV/SignupAbuseBlocking 14
This will wipe all the tracking data and re-create the tables, while preserving the add-on options and permission configuration. The old reports will be left dangling as this doesn't remove them, but those can just be rejected and ignored as they will not be used any more.
