What are your thoughts on fansubbing and scanlations?

anime, manga

So it was kind of hinted at in my last post, What is Goblin Cave? But I am currently doing some research into the history of fansubbing and scanlation in the anime and manga community, more specifically the yaoi and boys love side of things and I decided to ask people for their opinion over on Twitter and so far have been getting some interesting feedback.

So I want to know anime and manga blogosphere what are your thoughts on this subject?
