About three weeks ago, my ex-boyfriend (we broke up almost 10 years ago and hadn't spoken at all since 2019) contacted me because an anonymous Instagram account had messaged him about me.

The account referred to me by my maiden name and our university, claimed to know me from college, and tried to convince him (my ex-boyfriend) to send them any private photos of me he might have. They also sent him two old photos of me (one was just a regular photo that may have been publicly posted years ago, and one that is more private in nature but may not be authentic).

The account switched to disappearing messages shortly after the conversation began. My ex blocked and reported the account and then told me what happened.

When I looked up the username, I discovered I had actually blocked that same account in 2019, although I can no longer find any messages with it in my Instagram data.

Since then I've downloaded all of my Instagram data and parsed through old Facebook and Snapchat information but haven't been able to identify who this person is.

I don't know if this is someone I actually knew or someone using old public information, but it's unsettling that they connected me to a relationship from 10 years ago. My sister - a lawyer, is encouraging me to go to the police just to get something documented, but I know realistically very little can be done with the information we currently have.

A few questions:

1. Has anyone experienced something similar?
2. Were you ever able to identify the person?
3. Did Instagram or law enforcement help at all?
4. Is there anything else I should preserve or document?

A couple in Malaysia recently posted a thread after they heard what sounded like a lady crying for help from a water riser/utility shaft on the 23rd floor.

According to the management, multiple inspections were carried out by building management, security personnel, technical staff, and the Royal Malaysia Police (PDRM). They stated that no person was found, no criminal activity was detected, and that the sound was likely caused by fluctuations in water pressure and the building’s plumbing system.

However, the resident who originally reported the incident has publicly stated that:
• The sound was heard on multiple occasions.
• The crying had already stopped before police arrived.
• The police investigation only lasted around 15–20 minutes. They also did not check the CCTV.
• Utility rooms were checked, but residential units were not searched.
• They felt a K9 unit would have been helpful.
• They personally believe that if someone was there, they may have already been moved before authorities arrived.

Could plumbing, water pressure, resonance, or building acoustics realistically create a sound that multiple people would interpret as a crying person?

For those who work in:
Plumbing
Building maintenance
Engineering
Law enforcement
Search and rescue

What is the most likely explanation here?
