Hi there @lottiegarbanzo,
Thanks so much for getting in touch, and raising an important point to us.
We're really sorry, we appreciate it absolutely shouldn't have happened at all in the first place, but we can't see why your previous thread was deleted. The only reason could be that it was done in error - it's totally not an excuse but we've had a very very busy weekend at MNHQ. We have now reinstated it, and are investigating the advert.
