I cannot affirm this enough. If you can do good, do so without causing yourself the anxiety and the other person the stress/shame of trying to determine if they're "worthy" or "honest." Do it with an open heart and you'll be joyful. Most aren't scamming and will be relieved. Some are, and that's on them.
Evaluate charitable orgs, not people.
