I have this on good authority as of Sept. 11 (date in USA):
"The forum is under attack again even after we got things under control.
Please do not mention CloudFlare, we know, we have another system in place. This is a massive attack from hundreds of thousands of different IP's though user apps and browser extensions without those users knowing. This is not just one bad actor we can easily block.
The forum is operational, but it just can't handle the volume."
But my own observation is that our friends seem to have worked out a solution.
I have encountered what seems like a related issue at ARS Technica which is a science/technical news site.
I think that the AI bots are on the rampage.
