The Sun ignores its own successful campaign?

Today the Sun has an article about how someone who died from taking mephedrone AKA meow meow.

To the Sun's credit, it mentions that she took it after it was criminalised.

What it fails to mention is the Sun's role in the criminalisation of mephedrone.

I mentioned this on Twitter and at about 8.25 tried to post the same comment on their article. It - how should I put it - "got lost in moderation":

and at the time of writing hasn't yet been published.

Oddly, one from "Bob24" (date-stamped at 2:06PM, Oct 14, 2010), making a similar point, did get through albeit less explicitly, i.e. the Sun isn't mentioned, just the media generally...

It appears that the Sun is trying to whitewash the effects of it own campaigns. Why though? The Sun demanded an action and it was done. Surely the Sun would want people to know how much it influences government policy?
