SPEW

The Society for the promotion of Elfish Welfare was founded in 1994 by Hermione Granger, who believed that house-elves deserved to be paid, given holidays and even freed. Hermione went on to take SPEW further when she joined the Ministry of Magic.

It is noted that Hermione was the only person who believed that house-elves were suffering. Most of the people that Hermione asked to join SPEW refused, saying that house-elves led perfectly happy lives.
