Person won't halt- Help

... Thiiiiiiiiiiiiiiiiiiiis is gonna bother me SO. Badly- And also because...
I don't know how to Report. Mind me, because I'm dumb.

Oke, but on a serious note: Art Thieving person detected.

It makes meh sad that only like 3-4 people notice(Either that or people are afraid to say anything). I want to report but I can't seem to find the button.

What's even stupid, is that some of the art he posted... Have Watermarks of OTHER DEVIANTS.
... Do I sense a major red flag? *Points at art*

But anywho- Looks like this person's still posting after 'taking down ONE of the pictures'... So yeah, I'm sad.

And he doesn't have a deviant account, but my BRO can tell it's an obvious thief. That dude's posting things from dA artists, Pixiv's, etc...
