Social media is where many of the internet's trends happen.
When something is unique, has never been done, fun, and viral inducing, that thing can become a 'challenge'.
Knowing that many social media users are always crazy about new challenges, some opportunists have discovered ways to use a moment of craze to their advantage.
In this case, it's voyeurism.
The TikTok Silhouette Challenge is a trend that challenges users to post a clip of themselves using a distinct red filter, just like the animation in James Bond films' opening credits.
The challenge can then be attempted by dancing seductively to sexy music and mood lighting.
The trend started as a form of empowerment for women, in order to make them feel sexy.
Participants typically start their video in casual clothes and strike some poses in a door frame or something similar.
Then, the participants will transitions into a sultry pose in red lighting. To make a revealing contrast, participants can wear baggy or oversized sweats or clothing, to then switch to tighter clothes to accentuate their silhouettes.
However, since the point of the challenge is to show ones body and curves through their silhouette to make them feel good about themselves, many participants are wearing a lot less clothing, or stripped down to their lingerie, or even nothing at all.
What this means, some participants who attempted the challenge were bare naked.
Even celebrities have attempted the challenge.
And here, some people have found a way to turn that trend into depraved gratification.
Using specialized editing software, opportunists can attempt to revert the silhouette to reveal the posters' original form.
While editing software may not fully reveal everything, things can get pretty close.
Tweaking the hue and the color red, for example, and by changing the brightness and a bit of the contrast, as well as doing a little retouch here and there.
Opportunists can reveal much details that were otherwise hidden in the silhouette.
As a result, whatever the participants are or aren't wearing, may end up being seen.
On social media networks, there have been numerous posts and links to show how to remove the red filter and reveal the posters' bodies.
A few Twitter accounts have been found editing videos on request, and public shaming the people in them. A subreddit for this has also been created, and there are numerous tutorials on YouTube and elsewhere showing voyeurs can gawk at naked women.
After realizing this, users have started to warn others, to especially discourage women from attempting the challenge.
When the announcements were made, hashtags like #silhouette and #silhouettechallenge have collectively received more than 100 million views.
