Should topics / replies consisting entirely of whitespace be allowed?
Open, Needs TriagePublicBUG REPORT

Description

  • Visit a page with DiscussionTools enabled
  • Open a reply or the new topic tool
  • Enter only whitespace into the description (either a space, or linebreaks)

The reply / add topic button will blue and allow you to submit a comment / topic that will consist only of your signature.

The classic new-topic tool would forbid you from submitting a new topic with blank contents, but DiscussionTools autosigns which means we're actually submitting the equivalent of ~~~~, which it would allow.

Should this continue to be allowed, or should we forbid whitespace-only comment / topic body text? (Should replies and new topics have different rules here? For replies, this could be an ersatz "sign here" workflow...)
