Great topic! One of the things I've always thought would improve safety on platforms such as Facebook, Twitter and all the others is to make the sign up procedure more stringent so it's not as easy to set up multiple/anonymous accounts. I think if accounts (ownership) were verified at signup point it would reduce a lot of the problems we have with cyberbullying and abuse.
Sound good GamerGirl but how can this be done? It would need to be really easy because the companies won't want to see a drop off in signups due to lengthy signup processes. Great idea, it's just working out the minor details!
How about schools accepting that social media is a huge part of our children's lives and start teaching how to use it safely and effectively? This needs to be more concentrated than their current wide remit of 'internet safety' that seems to concentrate so much on sexual related safety. You'll be surprised how many teachers still don't understand social media!
