1. There's more shounen, shoujo, and hentai releases than yaoi ones on any given day. If you're going to bitch at fujoshi, bitch at the rest as well. One thing, I give the fujoshi
though that they know what to run a tight ship, maybe out of 50 or so groups, only 10 of them actively put stuff out. Yuri is still pretty small in Japan with only three anthologies that I can remember and the biggest yuri scanlator, Lilicious, is pretty fucking slow (and also refuses to one any of one of anthologies because it was aimed only for men).
If you're seeing alot of yaoi releases on a certain day, it's usually because it's a special day like today, which is White Day.
2. People will only translate what they're interested in. Seriously, you think Spore would've done all those chapters of Vinland Saga if he hated/was indifferent from it? No. If you seriously want to fucking read the manga, go take some moon classes. Like it or not, translators are not obligated to translate what you want. I personally refuse to translate anything other than doujinshis (Although I did think about translating Sayonara Zetsubou-sensei at one time but my weeaboo levels is too low for that fucking shit and I would miss 80% of the references). Shit sucks, but that's how life goes.
