I've used AoB myself, not for trophies tho. I'd consider it the safest, since you actually play the game and yes, wait a bit before sending, just in case. Aged accounts would probably be safer, got my 2-weeker iced for cheating on flash games. Don't overdo it and you'll be fine.
I like to use trainers; you actually play the game and most of the time you just get unlimited lives. With this option you have a lower chance of sending an unbelievable score, or sending to quickly.
There are ways to alter neopets games by using cheat engine and by doing so, you can play the enhanced game to gain NP, avatars, trophies. It is actually really simple after the first try and you can find many AoBs online. They differ from game to game, you see. But by using CE you can find the necessary AoBs and alter them in less than 1 minute and voila!, you can easily get the your desired scores. Just don't get too greedy.
AoB is safer then SS. You usually don't make mistake with AoB and if you use SS and enter the wrong number u are likely to be banned. JUST 1 wrong number
