Some really disturbing news about the silhouette challenge on TikTok.

It's a challenge that has grown quite popular on TikTok with some users gaining millions of followers from their take on the "silhouette challenge". The latest craze on TikTok, that has also spilled over on to Instagram, sees users pose in loose clothing for a few seconds while a song plays. Then after a few seconds the music switches and a red light filter appears on screen and users appear as a silhouette in the background. Usually the videos feature users wearing nothing in the second part of the video, or lingerie, or something similar. Of course there are also some very funny ones that make fun of the whole challenge too. This red light filter challenge has seen some TikTokers gain a huge following from their silhouettes - it's a craze that has taken over the TikTok world.

The issue with this challenge is that some people who are naked in their video (because they can't be seen with the filter on) are being subjected to a new "hack" first spread on Reddit that seemingly allows a person to remove the filter and see the unaltered image. According to Buzzfeed News, there are now videos online showing how to remove the red light filter so you can see the person without them being a silhouette. Videos showing users step by step guides on how to remove the filter used in the challenge were doing the rounds online, with some even appearing on YouTube before being taken down. Some Twitter accounts were reportedly even taking requests from people to help them remove the filter. Many users have taken to their platforms to spread the word and express their concerns over the new "hack."
