1. Make sure that you try to find a way to prove that he is really giving a beta code if you can if you dont find any good proof DO NOT ANSWER I REPEAT DO NOT ENTER.
2. Make sure that if someone puts up that it was already claimed and the author of the beta post says other way STOP DO NOT CONTINUE you will get your hopes way too high and ultimately may make you a real mad bro.
3. only things you can trust (for now) is website give way such as Superbots facebook/twitter, IGN, etc.
