I do usually highlight in bold a section in a post, responding below. As I did with David's thread post at the start of the thread. Other posters do this.
This was after QC made a big fuss over me copying & pasting sections of his posts & replying underneath.
I couldn't do this with Rob's post as his writing was already in bold.
Rob kindly responded to each of my points. So I had to do the same.
Other posters don't repeatedly post like you do over and over again in reply to the same post.
There is a specific forum rule that forbids it. You can't repeatedly post to bump up your post count. You also can't dilute topics and spam threads.
And you're right, I did make a big fuss about it and I still do, because:
(i). It's wrong and you know it's wrong.
(ii). It's contrary to forum rules.
(iii). It harms the Forum because it's annoying and makes it difficult for people to read and navigate through threads.
I suggest that when you need to respond to a post, you create a Word document or similar and put all your points together in that, then post it in one single post, or at most, two posts.
