Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      Very simple rule of automated learning: do not use any input that an attacker can control/supply in unbounded volume.

      Or even in a volume that will have significant effects on results. 4chan zealots will sit there and do a bunch of rote stuff manually if they think it'll affect someone, if automation isn't possible.

      Situations where attacker can control or supply inputs but only in limited volume are relatively few - mostly involve paying money or link to an established identity.

          I suppose cleaning the datasets after detection is easier when there's some auth/id. Doesn't stop these things from happening, and having effects before detection. I think in the coming arms race of ML vs disinfo, companies have to improve their feedback loops

          If Goog et al want their ML based interfaces to stay unmolested, will need to regularly self-test using whatever's new in news + contentious words like "jew" etc. Doesn't seem easy to automate, since it's a battle against an adapting adversary.

          Acquiring access to forums where disinfo campaigns are planned (e.g. discords for alt-righters) may be a doable but very contentious idea. Would probably only work short term until they go decentralized, and would reduce trust elsewhere.

          The whole point of my initial tweet was that all the ML they're doing is wrong. Kill recommended searches. Kill recommended videos. Even kill pagerank.

          Of course Google won't do any of that because they profit from it. The point is that they're stuck profiting from doing something inherently wrong/buggy/vulnerable to attack.

          Sort content by factual correctness and relevance to search topic, not by popularity contests.

          Well, that's not something Google can do. They're an automation company. Finding and evaluating factual correctness isn't automatable until humans are obsolete.

          It's a much more interesting AI problem than evaluating popularity, and plausible through cross-referencing with sources of heavy human efforts to verify (WP, peer-reviewed journal texts, political fact-checking sites, etc.) & moderate human-labor assist.
