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 46 days ago); 3/3 transport and email checks available (oldest recorded about 46 days ago). This is evidence coverage, not a probability that a website is safe.
