Uriel - From reviewing the thread, there is absolutely no indication at all that the thread is about a Future Update.
A thread in the Future Updates forum should be speculating about a Future Update, and should have clear indication of what the Future Update is that it is speculating about. A thread that simply says "Doom is coming" doesn't do that. A thread that talks specifically about the Tuska World Event, on the other hand, would.
When a thread has no content for constructive discussion, it is considered spam.
The FGU specific rules address this specifically so I've included them here.
from the Future Game Updates specific rules:
What is the Future Updates Forum for?
The Future Updates Forum is an awesome Forum where you can use your detective skills to the max. What do you think we’ll be releasing next and how did you come to your conclusion?
You could also discuss known planned updates. Did we announce in the News Section of the website that we’ll be adding spaceships to RuneScape? Think it’s a terrible idea? Then discuss it here. Please keep your threads constructive.
Please do not continue to post about the situation here on Forum Help, but use the Moderation Review thread, as Applejuiceaj has already mentioned. Thanks!
