Always i playing for a trophy (i use the AoB for flash games), the best case scenario in my experience is making like real life games. You're no a master in your first try, so tru to send some low scores like 'you're chasing' the trophy or getting better in the game. Usually it's the safe mode for not being frozen. And no SS or AoB 20 games in a month.
I have an account where i have SS'ed every single game trophy you can possibly score send, what i tend to do is put the score i want to send and when applicable (some games don't need it) but more often than not i bump the time the score sender gives me by 50-200 depending on the game, it seems to work for me, i have passed over 50 reviews. Might as well wait a little longer than risk getting banned in my eyes.
So in regards to your question you should easily be able to send little scores without any problem as i score send on a much higher level.
