I know grams info desk and the elpresidente vendor directory are great trustworthy sources for vendor PGP, But is there a site that collects vendor emails?
Obviously getting both from the same source is a bad idea, but if you already have a vendors key, or trust grams, it would be extremely useful to have such a site in times like these.
If a vendor wants to be contacted by email they'll usually have it listed in their PGP key.
