So it goes like this. You read an article, and want to post a comment. You spend 15-20 minutes writing a nice, lengthy, well deliberated response, and click to send it. The page reloads and you're brought back to the comments thread, but your post is missing. Assuming its probably a technical fault, you wait half an hour or so before returning. Nope, your post still hasnt appeared. Thankfully you had the foresight to save your post (or use a handy browser add-on to remember it) and you try to send it again.
"Duplicate comment detected; it looks as though you’ve already said that!"
The result - that comment is now essentially unpostable.
I've experienced this occasionally but have noticed it becoming slightly more frequent as of late, and have lost a number of comments as a consequence. Does this happen often to anyone else?
