Do you use any client?, the Enders client has a feature "autoheart", it prevents your toon to run into other players toons (that might have bad intetions towards new players, which sadly is very common here).
This besides other facilities like showing a char or a creature aproaching, etc.
Palisade is not protection, it just does for some days until it is discovered and attacked by toons with enough strenght to demolish them without the need of a ram and using little time.
You need a brickwall and also to check your wall every day for rams.
I was really tired of so much deaths, so I did alternate toons that i fed up with curios, and when the one I was using was killed i just started using one of the backups.
Good luck!, farewell.

Edit: Brickwall should be at least 25 tiles away from usable area. This advice was given to me to avoid snipers.
