I'm going to go straight to the point: THIS CHAPPY SHALL SHOW THY HOW TO WATERMARK THY MASTERPIECE IF THY ART THOU ARTIST.

Digital:
1. Crate an overlay layer above everything
2.Use a pen tool
3. Choose a color extremely close to white (recommended color-I mean shade: white)
4. Write @insertnamehere or just write your username it doesn't matter anywhere ON THE PICTURE YOU DREW. (Ex. Above)
5. TADA no nasty art thieves can take credit of your picture now

You can make the size of your name however large you want, as long as at least 50% of it is WITHIN THE PICTURE.

Traditional:
1. Write @insertnamehere or your username on a scrap piece of paper
2. Cut it out as a tiny strip of paper
3. Place it ONTOP OF YOUR DRAWING and snap a picture (ex above)
4. TADA no nasty art thieves can take credit of your amazing drawing

(Best part? You can reuse the strip of paper #ecofriendly)

Now you don't need to boil a user alive under comments on their 'art book', because you know that they didn't draw it and therefore why even bother? They want it for attention, in any form they can get it in. Be it hate or compliments, it doesn't matter to those creatures.

(Plus doesn't it make you feel so professional? XDD)

Of course, everything I've said up until now is my personal opinion. There are several other ways to trademark your artwork, the ones I've shown are just one of the many ^^
