There are series I love, and if I can buy it, I will. One Piece is my favorite manga, so I buy the volumes when they come out, or sometimes wait till all the volumes of an arc are finished and buy multiple volume. I do this because I want, and should, support the author of material, because that's how they are making their livelihood. Problem is, except for the big series that I read, a lot of the ones I read or want to read I cannot buy, or don't want to have to buy the volumes, because it would take up to much space, and I don't care for them as much. I've been reading through JoJo's Bizzare Adventure, and I would love to support Araki in some way. The problem is that only the third part is available for purchase, and that's the only way to support him.
In the states, there is the whole Shonen Jump Alpha, which you pay a subscription to read chapters of shonen jump manga a week after it was released in Japan. Problem is it's only manga from that magazine, and I believe the chapters that are put up are there for a limited amount of time. If they only ask for the series that can be found easily to be taken down, and make it affordable for people to see, then that is understandable, but still a bad move. However, if they ask for series that haven't been officially translated outside of Japan, then that's going to cause a big problem.
