Where they are registered
For the 63 with a registrar in WHOIS (80% 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.
| Registrar | Lookalikes | Share | Type |
|---|---|---|---|
| Dynadot | 9 | 14.3% | Retail |
| GoDaddy | 6 | 9.5% | Retail |
| Alibaba Cloud | 5 | 7.9% | Retail |
| Above.com | 4 | 6.3% | 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 Duolingo; it is not necessarily malicious, and none of these is a claim about who registered it or why.
