Explanation

When submitting a post with nothing in the body, we get this error:

Screenshot

But according to this page (formatting stripped):

HTML tags that do not appear on this list will be stripped out and not displayed if they are included in posts or comments. The source code for supported tags in posts can be found in posts_helper.rb, and for comments in comments_helper.rb.

So one can just enter something like this:

...to make the invalid tags get stripped out and leave the question with an empty body.

Edit: It appears to work even with supported tags, for example, <b></b>

Such useless posts can be flagged instead for speedy deletion

If such kinds of posts don't exist in the first place then the moderator workload can become lesser.

Validating length after stripping unsupported HTML seems like a good idea to me. In contexts where the minimum length is longer, this would look like a post (not a blank page) and people would want to know why the length wasn't enforced.

Monica Cellio‭ just tested with rev 2 of question and it appears to work even with supported tags (example:<b></b>)

So I guess all tags should be stripped, whether they are supported or not

There's already the suggestion of measuring the length requirements after converting to HTML (which would exclude the stripped out tags) to handle the problem at the other end of the length scale: False positive for 30,000 character limit which has a GitHub issue. Two approaches are suggested and the one that involves measuring after converting to HTML might solve this bug too.

I've updated that GitHub issue with a link here. Thanks for finding that, trichoplax‭.
