The biggest isssue is quality and accessibility. That's why we wish instead of trying to offer things to people as direct downloads and such (Which never last. There's no such thing as "unlimited bandwidth) that people are directed to our website where they can use our Bit Torrents and IRC channels. The less multiple different places to obtain the episodes the more bountiful the ability to get them will be.
Yeah. Direct Downloading is great... while it lasts. People can only really obtain it by either paying for it or stealing it (hacked ftps etc) and while the legality of fansubbing can be debated into the ground none of us want to be involved with "r00ting" and all that digital breaking and entering crap.
Anyway... Yeah. It sucks when people contact us and say "I downloaded your episodes from this site and they didn't work" or "It was slow" or my most hated "I used to download from a website and now it's gone. When will it be back up?"
So in the end it's hurting us and it hurts the people trying to download shows. Instead of that person seeding a torrent they're just ungratuitously downloading from some website and not seeding.
It's even worse when people re-encode our work because then people are turned off. "Oh, this quality sucks. I think I'll go buy these bootlegs."
And to answer someone else's question... I think the comment was aimed at RangerBoard. I don't really feel that place is a fan forum but more of a festering cesspool forum.
So, in closing... If you really want to help people get files then seed some torrents. It's the quickest and most effective way to make sure everyone gets to enjoy the love of tokusatsu and anime.
