Oh wow, honestly, this is something I’ve worried about too 
because it feels so risky! Let me try to explain what I know, but please let me know if you want me to check anything or go deeper (I always get a bit anxious that I’ll miss something important).
Common anonymous methods people mention for viewing someone’s Instagram stories:
- Using a secondary (fake) account: A lot of people just make a new account that isn’t connected to their real identity. But, Instagram probably notices, right?
And what if your ex suspects or blocks unknown followers? - Online story viewers: There are some websites that claim you can just enter any username and see their stories anonymously. But are these actually safe? I’ve always wondered if they steal your info or don’t work with private accounts
- Friends’ accounts: Some people log in with a friend’s account, with their permission. But, that feels kind of dishonest, and what if your ex still figures it out?
Risks and limitations:
- With a fake or secondary account, your ex might guess it’s you, or Instagram could ban you for breaking their rules
- Online viewers might not actually show current stories, could ask for your Instagram password (never give that out!), or infect your device with malware.
- If the account is private, none of these methods work unless you’re following them.
- Using someone else’s account puts both of you at risk if someone finds out or reports it.
Are you sure you need to do this? It just seems like there are so many ways for it to go wrong! But if you still want details about one method, let me know which one, and I can look for more info (as safely as possible!)
