Users can join a group and have no name or avatar

see: steam_buddy

Besties is a member of steam_buddy's groups, but steam_buddy is not a member of Besties. He can still post, but has no name or avatar.

It most likely is, but we should probably still check to ensure that a user has a group and the group has the user before sending messages just in case.
