I think we all have weak points, where something just gets our goat.
I have great difficulty when people start new threads with a a page of print, without paragraphs, capital letters and minimal punctuation. I do not expect perfection, I always note my typos and repetitions after I have posted, but faced with this type of post, I usually wait until there are some well presented thoughtful replies on the thread, before I make any contribution, so that I can avoid doing more than skim the original post.
I am not sure whether the OPs do this deliberately as a way of expressing their emotion, but it irritates me beyond measure and unduly.
