While we've mentioned that it is morally frowned upon to screenshot someone's Snapchat uploads, it is not necessarily illegal to do so. The legality of such an action depends on quite a few factors. The simple act of taking a screenshot is not illegal. Anyone who uses the app is knowingly putting something on the internet for you to see. Now, what you do with the screenshot is another matter. Aside from the possible civil repercussions (someone may have a viable lawsuit against you depending on copyright infringement), you could face some severe legal consequences. The first legal issue you could run into is what the screenshot includes. Assuming it's an explicit picture of a minor, just possessing such an image can get you in lifelong trouble. The second is extortion; taking an image of someone without their consent and telling them you'll share it if they don't comply with your demands has recently been in the news. There are other legal ramifications (we aren't lawyers, so we won't dive too deep into the subject) when taking screenshots of someone's content on Snapchat, but it's also worth mentioning that you could find yourself banned from using the app. If the person whose content you've captured finds out, they could report you to Snapchat. Therefore your account could get deactivated for violating the community guidelines.
