Where they are registered
For the 65 with a registrar in WHOIS (84% of all). Brand-protection registrars mostly hold defensive registrations made by brands themselves, so a domain there is more likely the brand's own than an imitation.

|---|---|---|---|
| MarkMonitor | 27 | 41.5% | Brand protection |
| GoDaddy | 12 | 18.5% | Retail |

Recent examples
The 10 most recent, written with [.] so they cannot be clicked. The brand's own domains and registrations held by brand-protection registrars are left out. A lookalike resembles Twilio; it is not necessarily malicious, and none of these is a claim about who registered it or why.
