The global blocking tool has severe accessibility limitations by having block messages only in one language. We need a solution to be able to provide useful information to all users regardless of their ability to speak English or not - which is the language exclusively used in global blocking messages.
A potential solution would be to address T243863, allowing us to create multilingual templates with information on the nature of the block and how to proceed with an unblock request.
Sites like Meta and Wikidata would also benefit by allowing translation of common messages used for blocking and protection etc.
