Not just .online, also any other domain Radix hosts. At least not for anything important.

What stands out to me:

> Earlier this year, Namecheap was running a promo that let you choose one free .online or .site per account.

I wouldn't be surprised if most of Namecheap's customers who used the "register a domain for free" discount were indeed malicious. Without seeing the results of whatever analysis Google did to flag this website, it's hard to say whether Google is at fault here.
