Someone is impersonating your business

Every form of it has a concrete reporting route, and the single best protection is to claim and verify everything that is genuinely you, so the fakes have nowhere to hide. Here is the response, and the lockdown.

Report it, and get ahead of it

• Use each platform's impersonation report, and if you are on the larger ones, their brand-protection tools, which can find copies automatically once you give them your real details and proof of your trademark.
• Include the fake's link, screenshots of your logo or content being used, your real account, and proof of ownership.
• Get ahead of it for free, immediately. Post on your real channels that a fake is circulating, share a screenshot of it without linking to it, pin a short "how to tell our real account" note, and ask your followers to report it too. This protects your customers faster than any takedown.
• If the fake links to a phishing site or store, report that to its web host or domain registrar as well.

Lookalike web addresses, and the lockdown

A confusable web address can be challenged through the registrar, through the formal domain-dispute process, or, in some countries, with a legal claim against cybersquatting. Defensively registering the obvious misspellings of your own name before anyone else does is cheap insurance. And the durable protection is the same as everywhere on this site: claim and verify every profile that is really you, get a verification badge where you can, trademark your name, and publish a short "these are our only official accounts and we will never message you for payment" page that customers can check.

The limit

You cannot stop fakes existing. What you can do is make yourself the obviously real one, so an impersonator is easy to spot and easy to remove, and your customers have a single source of truth to check against. In a web full of copies, a verified, consistent, genuine presence is the defence.
