It's not really necessary to be honest. I'm not really buying the whole length thing. I often quote many people I want to reply to in one post. Why would you need to double post? The only way I can see it being valid is if a thread hasn't been replied to and you need to bump it for whatever reason.
Thanks for your reply, this is mine:

However I do not consider double posting (only two posts) in a row for the quotes question 'post padding'... I have seen users posted 3-4 posts in a row, and I don't consider it bump because the posts are close to each other in seconds.
I have replied to those users in a few second, so it is not a bump to that thread. Have a nice day guys, it is not a problem for me but if all the other users can do/make double posting and their thread were not merged then this is the problem.
That's not really an excuse. You can still edit them all into one post or just make the post with multiple replies in the first place.
I don't find it wrong in anyway as once even I did it to post comments in a Signature campaign I was a part of but my second post was deleted even though it was not off topic and it wasn't merged. I don't get paid to post in my signature campaign but well it is considered as bumping a thread twice and so one needs to clutter up their post to avoid double posting or wait for another person to reply and then post another comment.
So there isn't a clear rule and each mod. "moderate" thanks to hi judgement (not a problem) but I will see if that mod will merge those posts from those users or not. This is why I have opened that thread (but first I sent a pm to that mod).
I don't think there's any rule on it but it's never going to be looked upon favourably when you have a signature as it's unnecessary, but I honestly don't know why you felt the need to double post in this thread. Looks like you're pushing your luck to me.
