I have been following, every single one of this threads and I haven't said anything because I know it was useless. Sorry that your friend cried but you have to realize he is here for hand outs and for upsetting people, you can't make him do the right thing so either try and take some sort of legal action or try to ignore it, by yelling at him and getting in trouble you are only hurting yourself, he isn't getting anything done to him that matters were you are putting yourself in a situation that might get you banned and prevent you from helping other people who will listen.
You said it yourself you tried everything and you can't force him to do anything, he doesn't want to give them up he doesn't want to care for them and i'm sorry to say but you can't scare or yell at him enough to make him do something.
I've been on and off this forum due to people such as this, and i've spent nights crying and nights being fed up with everything human, i've been sick to my stomach with people and all the crap they do to animals because they lack the respect for them, a lot of us feel the same way. He isn't going to listen, you all tried and you all know that. Instead of freaking and stressing out over something that isn't going to change you should focus on trying to help those who will listen and make a difference in the lives of the bearded dragon who have people who care.
I stated giving them to someone for a short period because it might be something if he thinks about enough he will feel safe with doing.
Also you might want to take a step back and think of this in a different light, its not hard to google pictures all of this could be fake and I personally think everyone should refrain from giving any more hand outs, he is obviously not using them.
