In 2017 AOL blocked emails sent to my @aim.com email account from blockchain.info.

It disabled the 2FA email blockchain normally sends to access wallet accounts.

Not certain if that was an action taken against me individually or if AOL blacklisted blockchain.info's entire domain for all email accounts. I think AT&T now owns TimeWarner which owns AOL. Maybe the change in ownership will compel AOL to reverse the ban. Or perhaps the opposite will occur. AT&T is raising DirecTV prices by $5. Perhaps we're seeing the effect market centralization has upon the cost of services, which is to make them more expensive and unaffordable as perhaps we have seen with healthcare in the USA as it has shifted to become a more centralized and monopolistic paradigm.
