A lot of people just take my artworks and slap them in every fan video without my permission or even a source link and credit in their description. In fact, it's not just fan videos: I'm pretty sure a lot of people just post my fanarts in their own frickin' gallery and blogs without, again, any source link and credit anywhere.
So what's the point of posting if people are just gonna do that to my artworks? They're more of bastardizing my fanarts than admiring my fanarts.
TL;DR: I'm sick of seeing a lot of uncredited and unsourced art flying around. I just feel offended.
