No, the infraction that the OP got a post deleted for was making two posts in a row in the same thread, (The posts can have different content.) not for making duplicate posts in separate threads. If someone feels that they must add more to their thoughts, they should just edit their current post or wait for someone else to be able to respond. Also, if someone wants to respond to more than one person, they should consolidate all their responses in one post, rather than post a string of separate posts for each response.

I'm not certain if the posts that you reported are against the rules. the only rule that I could find that it is close to violating is this one:
However, both posts are in the same Board.
