OpenBait lookalike domains missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

lookalike
check_lookalike_domains
Find lookalike domains of a brand's website: the brand's name with common words such as login or pay, on the domain's own ending (or on .com for endings like .co.jp), and, for most longer brand names, .shop names of the kind copied stores use. Checks which of them resolve in DNS and what their front page shows (a page using the brand's name, a redirect to the brand's own site, another live site, or nothing). It does not try misspellings or look-alike characters. Read-only. Same check as https://openbait.com/tools/typosquat-check.
