at least twice that I have noticed you have edited your comment after the reply has been posted, without posting any acknowledgement of same.

I do this all the time. There is always room for improvement, and notes about edits are ugly. I only leave them on comments that were later discovered to contain errors that matter for the discussion, and in that case I leave the errors in place, only pointing out their presence.

Act on caring about implementation of version history for the comments if you want a better alternative.

Also, I refuse to reply any more to any of your comments

Thankyou.

because at least twice that I have noticed you have edited your comment after the reply has been posted,

About 1/3 comments that I make I think of additional things to say as soon as I press enter. When I start editing within 5 seconds of clicking 'comment' I do not consider it necessary to write edit. Given the frequency that would be outright spammy.

without posting any acknowledgement of same.

I have added sentences to several comments here. Nothing has been removed. A few extra words have been included where they were missing, making a sentence outright ungrammatical. This is an acknowledgement and not an apology of any kind.
