That sounds like a competitor of yours manually submitting your site to Google for “impersonating” them or something. Anyone can submit URLs to Google to suggest it be blocked: https://safebrowsing.google.com/safebrowsing/report_phish/ Perhaps some overworked underpaid analyst had a lapse of judgement. I’m sorry that this happens to you.

wait, this actually makes things sound even worse because anyone who might not like your product can add it to google and google can sometimes be none the wiser and then add it to phishing link which could then lead to their domains (ie. any TLD's hosted by radix.website) being lost in void essentially unless you have verified the domain in google analytics and even then I would consider this whole situation to be so messy.

At this point, NEVER buy any radix.website TLD domains.

I am seeing pinggy had the same issue with their .online domain and this actually definitely caused hurt to their business https://news.ycombinator.com/item?id=40195410 (I saw this post from their comment in here referencing it)
