Being responsible in a crisis

It has been a trying start to the week and I think it matters to me that I talk about this without naming names because there are some lessons in here and it helps with processing it.
It isn't always easy to make friends especially online so the appeal of a ready made circle who when you read about them on page sound very much about what you like and also are about - age regression - is strong.
You are welcomed and shown how to find members so after a while you start to share pictures of cute things or calming 'stimming' moving images although you find some seem to hostile similar people with different group names but you're caught up  enjoying it.

Then yesterday I came to read a page by a leader of the group who calls for all these other groups and some adult kink ones to kill themselves which really worries me so I go the the  group page where the people in charge called moderators answer questions and I find three people in or group have said they are very upset about it.
I find the moderator swears at them for questioning it, condones that remark and goes to accuse anyone who isn't comfortable with that a person into adult kinky stuff and worse.
I start to feel sad, crying hugging my teddy as it's one of the nastiest mean things to say to people who it seems to me are so like us and I am struggling to think what to do.😢
I find the people they not like and leave an anonymous message saying what group I'm from and I saw this so they can find it and ask them to please do something as our group doesn't look or feel a safe place anymore not just for us but anyone. 
I see someone from them contact a register of groups saying what I'd saw and asking them to be put on list of not safe groups and why.
I decided to change my group, blocking the person who baited the other group and left on their page a message saying who I was and why I'd left my group for theirs which hurts but as this upset me so much I think for my own safety I need too.
It troubles me that I was linked by being with our group to what was said so I apologize for it to the group I am now  with and hope they will accept that.
I think the lesson the lesson I have learnt is it can be very easy to be taken in, not seeing the attitudes they have toward others and how that spills over into hurtful, threatening behaviour and that I can act on it to protect myself and others.
