This was announced on here many weeks ago, have a read of previous post before posting
Have you ever thought that some people don't monitor this thread H24, or work at the airport. I'd rather have information twice rather than not at all. There is absolutely no need for that arrogant comment.
A fair amount of info is taken from here by Routesonline
I think you seriously overestimate the role of PPRune here. Routes online have a very sophisticated intelligence gathering system from multiple sources. They haven't gained the reputation they have in the industry by just monitoring internet discussion groups but have good relations with most airlines.
For all sorts of reasons, they may choose not to post info straight away
