How safe are these flash games? I can see there are tons of people with the exact same score in them so they are obviously safer than most games, but are they so safe that you can do them all in one day or should you split them over days / weeks / months?
I wouldn't recommend sending them all in one day, but as long as you aren't reviewed you should be safe. The biggest problem you might have with sending so many scores at once is the scrutiny of other players.
