[Please Be Advised]
There are those of you who may already be aware, but for those who do not, please take the time to read through this.
Pictures posted to Pixiv are being reposted, without permission, to foreign sites. I believe those of you who have Googled your user page (your user page uses the format [http://www.pixiv.net/member.php?id=oo], using everything after the 'http://') already know, but most users' posts can be found directly linked to by sites that have reposted their illustrations.
Those of you who post illustrations may confirm for themselves below.http://danbooru.donmai.us/
*This is simply a warning.
I assume you got the bit about "demons" from 「あくまで注意を促すものです。」, but it's not using 'akuma de' (of devils), but 'akumade' (to the end).
Anyway, I'm not exactly fluent in Japanese, either, but that's the gist of it.
