Verifying against the live site and live WHOIS/DNS…
Common questions
Is responsive.us legit or a scam?
AboutUs doesn't label sites "legit" or "a scam": this page lists the dated registration, DNS, HTTPS, mail-authentication and safety checks we could verify, each with its source, so you can decide for yourself.
Who owns responsive.us?
Nobody has completed AboutUs's owner verification for responsive.us. That's true of most sites here — it isn't itself a warning sign.

We withhold an authority number until independent evidence (global rank, link-graph presence) has accrued. The facts we do have about this site are shown below — we'd rather say “not enough signals yet” than invent a low score.
Safety evidence
No unexpired threat-feed result; name-similarity check available (recorded about 75 days ago); 3/3 transport and email checks available (oldest recorded about 75 days ago). This is evidence coverage, not a probability that a website is safe.
