No information on why some domains still have the option, and some don't? I confirm seeing the same, btw.
So it's not functionally better or worse, not a security issue, doesn't actually cause using more resources... it makes it hard for us to determine who....!
This is consistent with a disturbing pattern, imho: Act first; inform and document later. I'm seeing too many of these "they took us down" for resources announcements for DH not to disclose/advertise warnings and limits more than buried in the wiki and forum, or something you find out from support, after it's too late.
What is the DH Mission Statement, anyway? We provide servers, make sure it's easy for us to track who uses their resources, and make sure nobody uses too much?
Has haste to expand become more important than their stated goal?
It seems you can have your cake (databases, scripts, terabytes of bandwidth and storage), but you can't eat up those resources too.
When is "eventually?" In Internet time wasn't that last year?
