Jehovah's Witnesses are subtly discouraged from contributing to any charities other that the Watchtower Society. While acknowledging that groups other that the WT may do "some good", JW's may feel that charitable groups are generally dishonest, wasteful or simply not doing things "Jehovah's way."

I will submit one, but I know there are many others.
