Has anyone had a customer track down their personal information?

That's a rough situation. The old filing is probably the weak link. You can sometimes get old records removed or at least have the address redacted if you can show a safety concern, but it depends on the state and the agency. It's not quick.

How did they connect the old license to your current business? Did you use the same name or email somewhere?

Email is the biggest leak most people ignore. Once someone has one email, they can pivot to old forum posts, data breaches, whatever. Changing the LLC won't help if the email stays the same.

I had something similar happen a few years back. A customer found my name through a state business search because I hadn't used a registered agent for an old sole prop. It wasn't a full doxxing but it made me realize how many little traces are out there. I ended up hiring a privacy consultant to do a cleanup. Expensive but worth it for peace of mind.

Changing the registered agent now is still a good idea, but it won't erase what's already public. You'll need to tackle the old records directly.

Did you report the customer to the platform? Posting your address is likely against their terms. Not that it stops them, but it creates a record.

Also consider a mail forwarding service or virtual address for future filings. Never use your home address again, even on internal documents that might become public.

What state are you in? Some have better redaction programs than others.

A police report might be easier than you think if you frame it as harassment. The customer posting your address could qualify. At least get a paper trail ngl.

I'd also think about Whether the customer is still a threat. If they're just venting, maybe it blows over. But if they're persistent, you might want to lock down your credit and set up alerts.

This is why I use a separate email for every business entity and never reuse anything. It's a pain but it limits the cross-linking.

Honestly, the genie is out of the bottle once your address is public. You can mitigate future exposure, but you can't unring that bell. Focus on making sure it doesn't happen again.

That's a bit fatalistic. People do get records redacted or removed. It takes persistence and sometimes a lawyer, but it's possible.

Also check if the old filing is with a county or state agency. Sometimes county records are easier to amend than state ones.
