2. Look at - Marco -'s post. I'm sure no one would be that dumb to not implement that feature and even fewer to not even see that either. Also worth a note that multiaccounting is not allowed.
3. Why can't you just play it online...? You're not cheating, no one is gonna watching you doing stuff like top players either. What I can see in this point is how your self-esteem is being too low to the point that you're scared of someone is going to watch your play. Keep in mind that unless your play is in the top 1000 it won't be saved into the server, and unless it's in top 50 it won't be visible to anyone except you and anyone that downloads the play in your profile (and no one's care enough to even do that either).
