So many false positives can happen here.
Most ISPs are already a pain in the ass to deal with. (Fuck you Charter/Spectrum). I don’t trust them to do their due diligence and implement this correctly. Or worse, abuse it.
“hey you pay for 1000/300 package. We detected abnormal traffic. Now you get throttled to 100/100. But still pay 1000/30”. Then they will drag on the resolution process until you give up.
