I think its important that once the dust settles here we don't just let this whole situation be forgotten. Our community has a huge population of vulnerable youth, a huge amount of which are lgbt. That makes us a huge target for potential predators. Try and be there for the other social outcasts that have found this fucked up place. This community has been there for me in the past and I know we can do good things.
If you notice a young friend going through something difficult, anything from an identity crisis to a tough situation at home please reach out and make yourself available. Its all to easy for those with bad intentions to take advantage of that vulnerability and the number one thing you can do to protect people is be there.
If you're struggling and need someone to talk to know that it is okay to reach out online, just be mindful that support should not be sexual. Support should not isolate you further and anyone that is trying to take advantage of your situation is not your friend.
Maybe this is preachy and unhelpful but I would just hate to see this happen again with another group a month from now. This isn't about nursey its about keeping young people safe. This may also not be the solution but I'm all ears for how we can actually help potential victims
EDIT: To clarify on the lgbt comment, I only bring that up because lgbt youth are much more likely to be victims of this due to online being the only place they can be themselves in some cases. Its great that our community can be a place for people to be themselves. A lot of these people cannot be who they are in their own homes and I guess thats worth pointing out
