'What Is This Thing' is an incredibly popular subreddit. It has over 1.8 million members, all helping people to identify the objects in their possession they have no knowledge of themselves. I have no doubt that one of the biggest reasons why this online community has gotten so massive is the fact that they constantly deliver.
With a few very rare exceptions, 'What Is This Thing' cracks one tough case after another. Show them a small round "shelf" in an old mailbox, and they will tell you it's for leaving change for the postal worker to add postage. Post a photo of a strange ceramic jar and they'll reply it's a stoneware bed warmer.

Like we've mentioned in an earlier article, the subreddit has a branch called 'Trace an Object' that searches for objects posted by Europol that are linked to child abuse cases. "We've had some luck in identifying some things, but there's more yet unsolved and more to come as Europol does release some new information every few months," the moderator team explained to us then.
At the time, the 'Trace an Object' subreddit had around 53k members but now the number has grown to 67k. So in a way, the more attention 'What Is This Thing' gets, the more help Interpol receives. Presuming people will find about 'Trace an Object' in the process as well.
#2 Small Round “Shelf” In Old Mail Box. What Is This Thing?
Answer: for leaving change for postal worker to add postage. USPS delivery people are required to have stamps and you don't even need to catch them to buy some. If you have a piece of mail without postage you can put it in your mailbox with cash and the carrier will bring back change (if needed) the next day.

There are other subreddits that are helping the public too. And they can work together on serious cases. For example, when user and college student shadybusiness15 took apart one of their extension cords, they noticed something wasn't quite right—there were mysterious wires and a SIM card with a serial number in it. Curious, they posted photos of it to both 'What Is This Thing' and 'The Reddit Bureau of Investigation', a place where people are passionate about solving mysteries as well.
Users quickly identified the mysterious parts as audio surveillance. The contraption connected to a phone number, which the owner could call to pick up audio in his room at college. Shadybusiness15 called the number but it was already disconnected. Shady business indeed.

#16 This Hollow Bumpy Thing Was In My Quarantine Care Package. On Either End Are 5 Small Holes Arranged In A Pentagon (Which Don't Whistle Btw).
Answer: Just asked my girlfriend who is Korean who says it’s from the health centre in Jeju island. The writing says “Metropolitan mental health welfare centre” It is literally just a hand massager, really common for old people To get one with welfare packs. Pressure points are really important to Korean people. So wouldn’t be surprised to hear they include one in the COVID care kit.
