Since the beginning of my career as an internet entrepreneur I'm facing the same problem over time - scammers and fraud that trying to parasitize on my brand or product.
Most of my products are e-goods or small SaaS tools.
The way scammers are troubled me:
The main problem is that customers who send money to fraud then complaining about my business, my service, and trying to get a refund from me.
Anyone is having the same issue? What should I do? How to protect my business from angry customers who are shilling about the refund and not aware they've been scammed? I'm getting loses on support and of course, all of these people are my potential customers.
you can do an entire keyword campaign to out them report them to scam site trackers, just broaddcast their names all over and see if any search for them wil then bring up their page followed by pages on google referring to them as scammers. Write a page with Q&A schema with questions like "are xyz.com scammers?" and give detailed yes answers. etc. You can fight back...
Find those copycats and list their links (nofollow, of course) on some warning page that you can send to refunders and say if you are client of some of those, you are not a client of mine. Make public post on whatever platform you see they use for promotion, say this is not me. etc
