Yeah, I've been using it for the past couple of years. The files download straight from MEGA or other trusted download sites. I haven't experienced anything negative like malware etc. so it's a thumbs up from me. They also have one of the biggest databases of raw manga.
P.S. TBH i'm not actually sure if we are allowed to distribute the links to manga raws from this website so if somebody could enlighten me on that it would be great ヾ(❀╹◡╹)ノ~
Mmmh, I'm not too sure ╥﹏╥ If you would like the direct link to the raws in the meantime though try this:
https://mega.nz/#!dHB1hBbS!2Fd15hmtkdGZ9vryVlzTvLpyV1rKckP7Y0FnxH-NxpA
Please do try to sign-up when you get the chance though as i'm pretty sure they won't like me distributing the link ヾ(❀╹◡╹)ノ~
If you are struggling to register, tell me the issue and I will try to assist as i'm not sure how you directly contact YaoiOtaku for issues such as this. If anybody else can help, please do!
