Mainly Twitter enthusiasts love drama there.
So the 'Merlin banning vloggers from vlogging' was a rumor started from someone who had "official Merlin sources" stating that Merlin would stop vlogging within weeks as a result of the TPWW incident. Merlin then invited Shaun to multiple media events and everyone has been free to vlog their hearts out ever since. The person a few months later deleted Twitter, due to their being too much drama on the platform. Returns a few weeks later........
The Blackpool one happened last off season I believe where a source 'leaked' that Valhalla was going to be refurbished and closed for the entirety of 2020. People once again on twitter were unhappy that, a source had leaked this to a small creator in the theme park fan base, and were sure the source was wrong and the information untrue. Spoiler alert, he was correct. Despite the informant wanting to leak the information, others in the community had said that jobs would be lost as a result and marketing campaigns ruined. Well I guess rollercoaster construction updates do the same thing but nobody complains about those.
There are just some mean people in the theme park community who just want to create drama.
