To add to the other answers you’ve gotten, “cycles” and “hertz” are both still used. The frequency (in Hz) is a count of how many cycles are in a one second period. A datasheet for an electronic device might have the frequency it’s compatible with listed on it (typically 60Hz in the US, 50Hz in Europe).

For some signal processing and protection equipment you’d also see a number of cycles listed on the datasheet - that will always be paired with a “at X Hz” clarification, because it’s functionally telling you how long the device takes to operate. For utility line circuit breakers, for example, “3 cycle” and “5 cycle” breakers are the most common options in the US, where 3 cycles translates to “this breaker will be fully open within 3/60 of one second of a trip command.”

The context of the quoted section of the article is about what an acceptable false positive rate would be, not about what situations drunk driving would be acceptable.

Scam bot operators will just use stolen credit cards - or even easier, iTunes gift cards that they get from the victims of their scams - to pay to “prove” that they aren’t bot accounts. For the fake followers/interaction bot “services” it increases the cost of operating, but I doubt they spin up a bunch of new accounts for every client - that $1 per account can probably be spread out pretty thin. I don’t see this solving the bot problem any more than prioritizing paid account replies did (it didn’t work at all for that).
