Whilst I can see (and to an extent appreciate) what the initial intent of that page is (was?), the fact that it's now become troll central is indicative not only that its already past its useful life, but it has also again proven that Facebook is again a haven for trolls and trolling; and not all of that is directly from whoever set up the page, but others who engage with the page.
I've no doubt that the person who set it up never intended to become as much a troll as they now appear, but I'm sure they cop so much shit every time they check their messages on FB now that's taken them to a place in their mind where their entire response mechanism is.. well.. troll. A person can only take so much shit from so many people before it starts to affect how they interact with others.
Sadly a bigger issue is highlighted here that is endemic to social media; bad behaviours breed bad behaviours.
At least back in the earlier days of the internet, you needed to invest in, setup and maintain a website, and unless it was hosted on a free service, you had fairly limited amounts of anonymity (and this is still the case). Now, people can create these pages with no real cost and greater anonymity all thanks to the platform that is Facebook. Facebook being Facebook are too big to care, so they have no interest in taking some control over what pages and groups are of actual benefit, and getting rid of those that serve no real purpose other than to defame and to bring out troll behaviour.
Teenagers already struggle to behave appropriately toward each other on the platform, with bullying and "keyboard heroes" rife on the service. The adults are starting to behave much the same in FB groups where they feel they can get away with such bad behaviour without any consequence. Ironically, Usenet in the 1990s was a useful internet service that started being overrun with SPAM and trolls; the fact that it was an unmanaged DMZ that provided anonymity brought out antisocial behaviours that took a perfectly functional and useful internet service and turned it into something that I doubt 95% of the readers of this message have never heard of anymore.
Alas, Facebook risks failure from the inside; it either needs to be more proactive in regulating the behaviours of its users, or the rubbish will drown out the useful content and the convenience of having a centralised "news feed" that aggregates content will be overshadowed. Its own demise (which will probably be a slow process) will then open the door for something new. That something new will need to take all of the positive elements (information aggregation, groups, apps) of a service like Facebook, and remove the negative elements (trolling in its many forms, better management of fake profiles, spam and so on).
Facebook are into being free, open and sharing information; all very important things, yet they don't temper this with much responsibility.
