# What does the sentence below, which is only visible in the edit mode of an answer I gave, mean?

In this answer I posted there is a "sentence" visible when you look at the end of the edit version of the answer (visible when you "push" the "edit button" below the answer). The sentence isn't visible in the answer itself though. The sentence can't be put here and be shown in my question by putting it in a quote form, by copy and paste or by just typing it. This is the sentence I mean:

<!-- The 6-character limit is plain stupid. Next poster, please remove this -->


My question may be obvious: why has this sentence been added to my answer in the edit mode. What does it mean?

That's a comment, using the meaning of the word from the context of programming. I can't find anything about that in the editing help page, but it's a standard HTML technique which is supported in Markdown. <!--stuff--> is a simple comment; if I remove the backticks from the markdown to get rid of the code formatting, it won't show up in the content.

Some anonymous user wanted to make a one-character edit, which is forbidden by the 6-character limit, and putting comments like that are a standard way of 'cheating'.

Ideally, edits which do not satisfy the 6-character limit through visible, useful changes should neither be made nor approved, since the limit is implemented to avoid such trivial edits in the first place. If you find yourself noticing such a typo like that, you could either leave a comment (comments are to suggest improvements!), or find other parts of the post which could be improved. But frivolous HTML tags are certainly a bad idea. If you have >2k rep, you can technically do it, but you should avoid it (the 6 character limit is not implemented for those with the editing privilege), because your edits will still bump the post to the top of the front page.

Now that it's there, it's an ugly blot in the markdown, but I still don't feel it's worth bumping the post to the front page by just removing that comment. If you, or any other future editor has a more legitimate thing to change, it would be a perfect opportunity to delete that bit.

• For this specific case, note that the edit was not made by a site user, but by an anonymous visitor who clicked 'improve this answer' - this is indicated by the Community signature on the edit. Thus David's emphasis on the review of those edits (which you can get to via the "edit approved" link on the revision history). Jan 13 '19 at 21:49
• @EmilioPisanty I've italicized the bit that the user was anonymous, and I've made the phrase which indicates that such edits should neither be suggested nor approved in bold.

• I think the formatting is overkill - it was just being explicit in including edit reviews. Feb 14 '19 at 8:58
