If you’re on the social network, you might have noticed a few friends posting mysterious messages in the last few days.
Two years after the Ice Bucket Challenge, we’re still being asked to sign up to viral challenges on Facebook – although these days they’re much more subtle.
Whether it’s telling your Facebook friends what colour your bra is to raise awareness of breast cancer or doing 22 push ups for soldiers who suffer from PTSD, they usually come with lengthy messages explaining why they’re so worthy and why you should be copying the post on your own timeline.
But a new ‘challenge’ going viral is rather more cryptic, offering no explanation whatsoever.
People have been posting black and white photos of themselves on Facebook with the caption ‘challenge accepted’, often tagging a friend in the comments to challenge them to do the same.
On first seeing the message, you might think it’s just an attention-seeking post by that girl from school you’re still friends with on Facebook.
Once you see a few more similar posts, you might start to think there’s something going on and you’re not in on it, resorting to Googling why on earth people are doing this.
The problem is, this might not offer you any enlightenment either as there doesn’t even seem to be a solid explanation as to its origins.
Most people are saying it’s to raise awareness of cancer and the idea is to fill news feeds with black and white photos to ‘fight against’ the disease.
But it doesn’t appear to be affiliated with any major charity, and donations or any sort of action aren’t being encouraged either.
What’s more likely is that someone started it with good intentions of raising awareness and the details got lost somewhere along the way, or the reason was introduced at some point after it had gone viral.
Some are sharing their photos with an explanation about why they’re posting it – to ‘fight against’ the disease – but the message has been lost in most posts.
The trend has been spreading around the world and was incredibly popular in India at the beginning of August, finally catching on in the UK in the last week.
So if you’re tagged, now you’ll know the idea behind it. If you actually want to share a nice monochrome photo of yourself then go right ahead, but it might also be worth including a link to a charity’s website at the same time.
