It’s been discussed and requested before, more than once e.g.
While I understand that soft-delete maybe useful, after some period (e.g. 1 week or month) it would be nice if deleted things were actually removed to save space and also ensure legal compliance e.g because some thing illegal was posted, or personal details need removing for GDPR compliance.
Having to log on and run a rake task to replace the message with ‘this has been deleted’ is a bit naff.
