Look, not trying to be snarky./... apologize if I was... but the convo at resetera is based on people thinking the user DB is something that will be 'sold off', as if that precious information is somehow going to be siphoned off to others now that MOBA owns the site.
There is value in having a userbase; hell forums are entirely based on that as the users generate the content (as opposed to say, a Kotaku, where the comments under articles are not a significant portion of why anyone sees an ad on the site.) But the DB itself is not some shoppable item; and honestly having a "primary" email address isn't all that relevant to advertising. I dont use my work email address anywhere on the web.. hardly anyone does... everyone on the planet uses gmail or some derivative (exaggerating, but it's a massive percentage.) That's because they aren't permenant. So for ad tracking purposes, my work email I dont use anywhere else, including my credit card, on other sites where they'd want to track my behavior, etc. is not some extra value. In the eyes of the ad trackers, I become actually MORE anonymous using an email like that.
Anyways covno is more in context of resetera freaking out over that DB being sold off; if ad services are expecting web sites to supply a hash of your email address for instance, why would anyone think Cerium wouldn't do that? Very few won't if that is what is expected in the future.
TLDR: No matter what "Value" there is in the user DB, there's no reason to think MOBA will handle the information "worse" than Cerium and co did/were going to.. hell.. if anything, they'd likely have better / more professional handling of the data.
