I love services that have not a single person as a contact/responsible for the site. /sarcasm

It's a red flag if you hide behind a contact form with no reachability beyond that whatsoever.

And as other said: 99.5% accuracy means you should have millions of working fingerprints, since mine and others are faulty as hell.
