Our team is discussing this internally, and curious about others

others of course, identifying themselves correctly..
But then there are those on Digital Ocean or AWS that use throwaway
domains, or no clear identifiers..
While the idea of 'validating' an email address seems like a logical
thing to do, some of the list washing services appear to be just used to
wash old lists, or email address harvesting..
What is the position of the industry on these issues..
Would love to hear opinions and practices being used on list washers..
It is interesting how quiet it is on this topic.
A quick review of logs here shows a new trend of the validators using
Google and Microsoft as their sending platform. I would guess to reduce
the likelihood of being blocked.

Perhaps in addition to our large providers considering the inbound
attempts of validators as BlockOnSight, they can also consider the
validators outbound efforts as BlockOnSight also.
