Looking for help with a harassment case
I’m looking for advice on how to analyze an Instagram account that has been repeatedly sending unwanted and harassing messages to someone I know.
I’m interested only in available information and OSINT techniques. I’m not looking for private information, hacking, leaked databases, facial recognition, or anything that would expose someone’s personal details.
I’d mainly like to understand what kinds of publicly visible indicators can be used to determine whether an account has connections to other publicly visible accounts — for example:
username reuse across public platforms
publicly visible profile information
reused or publicly posted images
publicly visible posting patterns
other open-source digital traces
The goal is to better document the harassment and understand whether there are obvious links between publicly available accounts. I will not publish or share anyone’s private information, and I’m not looking to contact or confront the account owner.
If anyone can recommend legitimate OSINT methods or tools for this type of public-source analysis, I’d appreciate it.
