For those who don't use Glaze or Nightshade here's a link to both. I'll make this post pretty later, just need to get this posted for now.
Glaze --- Nightshade

And for those who don't know what these are here's a quick explanation.
"... the difference between Nightshade and Glaze. The answer is that Glaze is a defensive tool that individual artists can use to protect themselves against style mimicry attacks, while Nightshade is an offensive tool that artists can use as a group to disrupt models that scrape their images without consent (thus protecting all artists against these models)." <--- from The Nightshade Team.

I personally use Glaze on everything I make, sketches included before uploading them ANYWHERE. From what I can tell it works even if you use it on the lowest setting. You don't have to use either one but I highly recommend it. It does add a...film/texture on top of your artwork that can be visible. It's a small price pay if you ask me.
