The above templates (SD, speedy, Badname) expand to full speedy deletion requests.
In particular, this is better practice than just blanking the category page. Blanked categories end up on Special:UncategorizedCategories, which is largely handled by non-admins who cannot delete the categories in question.
If you believe the content does not meet the criteria for speedy deletion, you may replace the speedy deletion tag with a regular deletion request (if the content has not been deleted) or request undeletion (if the content has already been deleted).
All your uploads, including deleted ones, are listed in your upload log.
