<p>I have been in this situation on several other SE sites, usually not meta (the meta seem to be more tolerant of many comments, as they are often discussions anyway).</p>

<p>The only system initiated action that I am certain of is that the comments will be collapsed at a certain point, for brevity. In other words, the first n are displayed, and the remainder are visible only after clicking a system generated "more" or similar. Then these are uncollapsed and visible.</p>

<p>I have been prompted by the system to move to chat, for comments on answers, but that was a very long time ago, and I haven't found an FAQ on meta SO for details. Etiquette seems to be for someone to suggest a transition to chat, particularly if each comment is multiple lines and there are five or more comments. So many comments on questions truly is to be avoided, as it makes it confusing and tiresome to read all of them before answering, sifting through the relevant and the less so. For comments on answers, it is less of a problem, but still should be limited. </p>

<p>Consider this option, if possible: Delete any of your prior comments, if they were truly extraneous or mistakes, e.g. ooops, I mean this, and replaced by a second comment that corrects and replaces the earlier one. That can happen easily enough due to the five minute time limit on comment edits. Just as long as the flow of the thread is not broken by the comment deletion (you can delete using the little x at the end of your comment), that may be helpful for preventing a trail of comment debris. </p>

<p>It also helps avoid the need to move to chat. Nothing wrong with chat, but as someone else mentioned, that is not always possible for every user, depending on firewall status, possibly other factors.</p>
