especialy the foundations which are in abysmal condition
You only need to look at the things to see what state they're in. And nearly every time it breaks down there is something wrong with the foundations.
This is, potentially, a libelous situation. You cannot make claims like that, what you are saying is potentialy damaging to Alton Towers and especially as they are not true.
Health and safety has become one of the worlds top priorities in recent years, not just because of duty of care to customers but also because of the really sudden growth in accident and personal injury law firms. If there was anything remotely or potentially wrong with Nemesis' foundations or any other part of the ride, it would be shut down immediately.
If you had posted your "facts" in a more public place AT would be well within their rights to pursue legal action aganist you for those comments, they probably would be within their rights to do so anyway regardless.
May I advise if you don't know anything about the subject that you don't say anything at all.
