Tangent: You know How everybody has to keep explaining "web3" over and over again? Twitter threads, deep dives, YT explainers, etc? Nobody had to spend much time explaining "web 2.0". You just saw Google Maps after MapQuest or InstantDomainSearch after whatever else was there, and you instantly got it.
P.s. sorry if I'm totally wrong about this could be from some other site for all I remember now
Do a whois search, maybe cache the results a bit. Have affiliate agreements with some vendors. And scrape domain squatter prices.
Even a lot of registrars do this.
TLD-list (among others) does everything you do, better.
Because 1) you don't expect this to happen (confidentiality) 2) you're still setting up your company/idea which requires other administrative tasks which require time.
They want you to impulsively buy a domain out of fear of it getting hijacked.
Otherwise you just decide which domain search you trust and hope your domain remains available.
