No, I don't think that amounts to spam or is against the rules.
I also find it difficult in some cases. Posting everything in a single post makes it very hard to read, and quotes get too long, while making one post for every quote is pretty too much.
I would say, find a balance.

I know but (I think) this is the first time I have made two consecutive posts only to make comfortable the reading or legibility. There is not a second "fine".
If you do it with a signature it can be seen as 'post padding' to raise your post count and get paid more.
I'd avoid if possible.
So now I should report all the users are 'making double posting", do you know how much users I have seen do post in this way? I don't want to write their username here... I will report all their posts now and see if they will merged in one or not. If they will not merge in one unique post I think this is a sort of discrimination.
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.
Thanks for your opinion guys!
