I've been on CM since 2012. I've never changed my screen name. I've never had issues with bullying or stalking. I've never created drama or lied about my life, and my experience has been tremendously positive.
Here's the deal: there are all kinds of groups. Groups for all kinds of people. There are "support" groups, which are privately owned. Anyone can make a group, so if they want things managed a certain way, they can do that. If they want love and support and a bunch of yes-man crap, they can make that, or find it. There are a lot of groups that offer that sort of thing. I'm in one. If the pre-existing ones aren't cutting it, make Step-Moms United or Special Moms for Special Needs or Kumba-Freaking-Ya or whatever.
There are "b****" groups that are there for drama and entertainment. The biggest one is Mom Confessions, but there are many. These are not groups to look for support. People are a**h****. It's fun and funny, but if you're an a**h*** or an idiot under your screen name, people remember and catalog everything, and it will follow you. Is there bullying? Yeah. I guess. There are sh**** people everywhere. I've never had an issue, and I can be a real d*** sometimes, or say some pretty stupid things. Then again, I don't get my feelings hurt easily, and understand that it's all superficial b***sh** the majority of the time, anyway.
I've made some amazing friends on this site, that are on my Facebook and that plan group video chats, support the hell out of each other and me, and we've all talked about meeting, some of us have met and been part of each other's lives outside of the internet.
You get what you put out. Whine all you want, the site isn't going anywhere, and most of the people complaining are back under a new screen name, because no matter what they say in their exit post, they tend to come back once they realize that they aren't going to change the site. They need to learn that the universe doesn't cater to their whims, and if they want something specific, they need to go out and find it instead of changing what's working for the majority.
