The author contrasts this with the ease of archiving email lists, a process they are personally engaged in for lists like lightning-dev and bitcoin-dev. They point out that email archives offer stronger authentication methods, such as PGP (Pretty Good Privacy) and DMARC (Domain-based Message Authentication, Reporting & Conformance), which bolster the credibility and authenticity of the archived content.

The author suggests that there is no apparent way for delvingbitcoin.org to match the level of security and authentication that email list archives can provide.
