I just think Alton need to make sure they know their own rules before outing someone on social media over something that is technically allowed. Seeing as the attraction says at owners risk, the website permit unless stated at the ride and staff have seem to say yes. If they are going to start picking people out on social media, they best start with the making sure their rules clear.
Tho all this is of the back of a twitter account who outted their picture to alton, trying to be all smug it seems.
