Theres been a lot of hacking on animal jam as a trade off of all the scammers, one way I protect my account is by using my parent account. On the parent dashboard you can enable/disable the ability to send gifts, trade with others, chat, use jammer, wall, and even the whole account. I always disable my account after I have logged in.
Heres how:
Login to your parent account
Find the gold AJ paw icon, second tab
Find the "account enabled:", turn off that, red button means the account is disabled
This locks your animal jam account, so if someone tries to login to your account, a message with "something went wrong will appear", AJ will not explain what the issue is. So, make your hackers mad they can't get in!
Please note: You will need to re enable your account in order to log back in again. Every time you disable your account, you will have to re enable it, I do it every time I use AJ just to be extra safe.
Hope this helps, Jam on
