Curl did already tend to get a decent number of junk reports from people who just didn't know what they were doing, but this was limited to the number of productive idiots who focused their productivity on curl specifically. AI allows significantly less motivated idiots to create substantially more workload, and therefore upgrades this phenomenon from a minor annoyance to a big problem, one that may just render publicly submitted bug reports not worth the project's time.

(And no, curl does not have a huge pool of potential maintainers to pull from on this. Open-source software in general suffers from a big lack of manpower, especially relative to the popularity of the tool)
