Please answer without waffle or prevarication.
The comments that I can see on the two linked posts appear to be (properly) addressing the content rather than its author, critiquing or requesting improvements to the content. This seems to me to be an appropriate use of comments. The posts the comments apply to are long and complicated, so it seems reasonable that a user could find many points worthy of critique and address them each in a separate comment. It does not seem that the comments in question are abusively repetitive.
Assuming that the comments, individually and collectively, are justified, it shouldn't matter much how much time passed between their being posted. Communication on Stack Exchange is asynchronous.
Suggested appropriate responses to such a large collection of comments:
If you see that the comments describe genuine room for improvement in your posts, edit the posts in question to improve them as suggested in the comments or to remove the issues dealt with in the comments.
If you disagree with the critiques offered in the comments, respond with your own comments, explaining where you disagree.
If you need more information from the commenter to understand what the comments are getting at, respond with your own comments, asking for clarification.
If you disagree with the critiques and believe that they are so off-base as to not require a response, ignore them.
(A priori) Write posts as clearly and succinctly as possible. The more concepts and words in a post, the more possible hooks for critique.
In cases where [you believe] some or all of the comments are, in fact, abusive, the following modes of response are available:
Add a comment politely asking the author to desist from the abusive behavior, e.g. "Please keep your comments focused on the content here, and refrain from trying to evaluate me as a person." I would recommend usually not going further than one comment down this road, since a long stream of comments on the topic of whether other comments are abusive or not becomes an off-topic blight on the post.
Make a similar request in Chat, where side conversations are welcome.
Flag any and all comments that you consider to be abusive of yourself or others. If it's not self-explanatory what's wrong with the comments you're flagging, or if you're trying to bring attention to a collection of comments as a body, use the "other ..." option, and then write a sentence explaining what you're objecting to. This will bring the problematic comments to the moderators' attention.
