Just use your common sense. The "trust" or "activity" levels may give a a hint about the trustworthiness of a user.
Activity should not be used as an indicator of trustworthiness, all it means is that the account has been around for a while and has had a fair amount of posts.
Trust is only good if you have a well kept trust network.
