Although it looks like David has enough signatures from other sources now, I'm adding it for posterity. I have interacted with David using his present e-mail [1] and one of David's previous keys [2], on numerous occasions in 2012, 2013 and 2014 by sponsoring one of his packages. His application key [3] has a valid GPG signature from key [2]. In 2019, we interacted briefly using key different from [2] and [3]. In 2020, I have interacted with David using his e-mail [1] and his DD application key [3] by receiving signed e-mails from him. I have additionally verified that, in 2020: - David can read an e-mail encrypted for him using key [2]; - David can reproduce bits from our private communication in 2013 in a signed e-mail using key [3]. Therefore, I without a doubt conclude that David is in possession of e-mail [1], keys [2][3], and is the same person I've interacted with starting back in 2012.
