What I wanted to say: losslessclub accents on quality.
Of all accessors of WCD I believe only NWCD tries to pay attention to it - don't know if they succeed.
Anyway now losslessclub is more than twice bigger than NWCD in aspect of lossless music.
And they have much tighter standarts for quality. I believe they check every log before torrent gets approved, and there are no torrents without logs.
But LC is almost not growing. I believe mainly because of their tight standarts.
