Those are not really "posts in a row" in the bad sence.
They are "daily updates / daily info / daily news" so they should be in different posts. They are ~24h apart ...
The fact that a few consecutive posts from a thread belong to the same user is not always seen as "posting in a row". The users that you mentioned are not newbies so it was not me who handled your reports but FWIT that's just my 2 cents
