Can an angry customer use my business information to find my personal identity?

You're not overthinking it. If your name is on the public record as organizer/member in Wyoming, that's a direct link. Wyoming doesn't have a strong privacy statute that hides member names on the creation documents. The registered agent only shields the address, not the name.

Wait, is Wyoming supposed to be the anonymous one? Because I keep seeing YouTube ads saying so. I'm genuinely confused.

The whole "Wyoming is anonymous" thing is mostly marketing. They don't publish the annual report names, and you can use a nominee organizer, but the initial filing still often leaks your name. It's not Nevada or Delaware levels of disclosure, but it's not a magic cloak either.

Unless you used a nominee organizer service. If you're the one who signed the articles as organizer, and you used your personal info, then yes, he can, if he knows where to look. Does he know your LLC name?

How did he even know it was a single-member LLC? I've had angry customers threaten to sue, but they never seemed to understand what an LLC even is. The average person can't parsd that.

If he wanted to, he could. But for a $30 order? People with that kind of fixation usually burn out before they file a public records request. You're probably fine in practice but as a matter of exposure, your name is out there. The easy fix is to re-file using a different organizer or use a nominee service going forward. But the past filing is still on record.

Compliance tip: check your state's annual report filings. Sometimes you can remove your name if you list a registered agent as the "contact" or use a manager-managed structure with a separate manager entity. Not always, but worth a look. Also, the bigger threat is if he knows your real phone number or email, which he might from the order. He could Google that. Forget the LLC.

That's thee real weak point. LLC records are public, but the effort level to get them and link them is high. The email to LinkedIn to county property records pipeline is trivial by comparison. Clean up your email footprint before you worry about the LLC.

lol @ "show up." He's not going to show up. He's going to leave a one-star review and go back to watching Netflix.

You can pay a service to file as the organizer for you. It's like $300 or something. Not free, but cheaper than years of anxiety. Might be worth it if you're really worried.

OP, if you're genuinely scared, don't just Rely on forums. A consult with a privacy lawyer might cost a couple hundred bucks. There are also walk-throughs on how to redact personal info from some business filings after the fact, but it varies by state. New Jersey isn't great for privacy, though. Wyoming's better but still requires you to file a change if you want to use a nominee going forward. But if he's got your email, that's a direct line.
