I don't think this happens to very many people, so I don't really see it a necessity. However, it would be nice to have this implemented. I would much rather have the feeling of being invited to a group rather than just placed in one. It gives the recipient a feeling of independence and control.
On another note, I think that awards should be removable by users themselves. I also think that we should have an awards showcase to replace the current one that we see on our posts. This is where we may show off only our best and in the order that we want. Both of these solutions could free up the time of staff having to rearrange and remove people's awards all the time.
