Do you believe everything you read online?
The truth of the matter is that, despite the misleading title, the article says nothing about it being invasive -- only prolific. The specified biostatus in some areas has been called "invasive" -- but that's from individual observers who confuse these terms as well. As your referenced page includes this note: "Some scientists have found evidence which indicates that Acanthaster planci outbreaks have been an integral part of the ecosystem for at least 7000 years on some reefs (Walbran et al. 1989, in Keesing et al. 1992)", I'm inclined to say that it is just an occasionally prolific species.
Invasive implies it came from somewhere else -- i.e. expanded beyond its natural habitat, either intentionally (roi - Blue Spotted Grouper or taape - Blue Striped Snapper), unintentionally (Zebra Mussels to the Great Lakes), or in an unknown fashion (Lionfish on the East Coast).
Just because a species is prolific does not make it invasive.
That said, the fact that man meets most (all?) of the definition of invasive species, but is not included in that database does not encourage me towards believing it is a complete list.
You have yet, again, declined to respond to your initial allegations of the illegal activity. Please either rescind your accusation or defend it. That is a VERY not-nice thing to accuse someone of.
