Regarding the Youtube contributers, then I have to agree some appear to be disrespectful by posting videos of staff members telling them off or whatever but I be shocked if any of them are actual proper horrible scumbags in real life, just more frustrated at the injustice of not being able to undertake there hobby because of the strict rules regarding photography/filming.
I'm sorry, but I have to disagree here...
There is no "injustice". Nexus own the system, and it is private property. And whilst I can say the ban is not something I totally agree with, Nexus and their contracted operator have a right and arguably a responsibility to control who is doing things such as filming. Nexus are within their right, and the photographers need to respect this instead of posting rude and abusive comments on YouTube, and even in some cases making rude gestures at CCTV cameras and behind the backs of staff.
I'd be willing to bet that staff who have to undertake these conversations with said people, who then respond with a less than mature and polite attitude are less than pleased by the whole situation. At the end of the day, they are doing their job.
Having met one of these individuals in person briefly (and seeing him getting the previously mentioned lecture at South Gosforth), I can say he appears to be a decent and reasonable person. However, the rules are the rules, and not getting permission as and when you want is not a defense for breaking said rules.
If anything, the staff are being far more than reasonable by not taking the matter further, especially with those who are now known to them for repeat incidents.
