You're absolutely at risk of this.
If you're added to the big bad google blocklist that all major browsers use, which of course is automated, anyone visiting your website will get a big red screen saying "this is a scam please run away".
This happened to my own gitlab instance, which sees around 5 unique visitors a year, and it has happened to popular websites.
The only recourse is to report the issue to google, who, if they feel so kind, will unblock your domain again. Oh, maybe I didn't mention - this block applies to the entire domain. I had the gitlab on git.example.com, and so *.example.com and example.com were all blocked entirely, on all browsers, for everyone in the world. Yes, you can click on a button, and then a tiny link that says "im ok with getting shafted by this scam site" or some such shit.
