watermark your shit
pics clips tiktoks facebook everything just fucking do it
bc dudes don't just steal porn from sex workers, mmkay? they steal your selfies and your new cosplay pics and your family/friends/pets pics and any other content that gets them going and they jerk off over them and upload them to sites for others to jerk off over too.
it won't stop them from stealing them, tho ppl have had some success with annoying watermarks and censors/edits, but it may help you with a DMCA takedown if it comes to that
privating your accounts also helps, since you can control a little better who follows you and gets access to you and your media
