With a great shard comes a large population and with a large population comes a few jerks. Just be careful who you deal with and eventually you learn to spot the jerks easily. I always kept my rare/expensive stuff banked or locked up in a private house away from even real life friends who played and I've never lost anything to anyone except a few bags of reagents, armor, etc.

Just know that there are people who want to try to backstab and plan accordingly.
