My 2 cents ... I agree that this was a minor event in RuneScape history.  It is already being forgotten by all but those who want to sensationalise it into something it is notm i.e. significant.  It is well covered in the construction article in the history section.  The video is not verified as authentic.  I've seen it, and it appears to be highly edited, which could drastically affect its authenticity.  Jagex has acknowledged and fixed the problem.  The coincidence that it happened on a specific date is just that, coincidence.  No one but the vandals who keep changing the article calls it the 666 massacre.  That's just silly.  Get over it and let it go.  It is not significant to RuneScape or to anyone over the age of 14.
