I usually browse the front page/ search keywords that are commenly stolen (anime, anime girl, wolf, neko etc bs...)

then i just look for things that dont look right (or look too right?)
* The most obvious if Ive seen it before on the internet somewhere
* Or if I know its on DA
* I click every mind blowing piece of art no matter what, either to comment or double check
* Anything that looks "colored over" especially in paint
* Anything with words added to it especially in paint
* Any piece that is *exceptionally* better than everything in their gallery (if their gallery is all pencil stick people than studio e.go! girl might not belong.
* Any piece that is in a completely different medium from everything in their gallery
* All the pieces are in completely different styles
* Anytime someone says their full name and the signature on the art is...not that name?
* Any piece with some amazing skill in one part but fails at basic design elements in another part (amazing wrinkles in clothes but no face on a person DDDD: wheres her face?)
* Any piece that is cropped strangely (especially the bottom where the real artists name a website, or company logo might be)
* Tiny images
* Low resolution
* Newer user
* Weird or vague titles (such as just calling a picture 'anime girl' or something)
* Vague or obvious descriptions of how the piece is made(such as I made this with the computer or I made this in photoshop)
* Vague or obvious artists comments ( such as HES MINE or a lot of the time just '...' )
* A user defending the fact that they DID draw it (if its your art you dont beg people to believe that you drew it ya know?)
