We implemented CrowdSec for bot/scraping mitigation. The architecture is sound, but it ended up having an unacceptable false positive rate for us. This may be an issue with any kind of IP reputation approach. After a couple of months of work getting it ready to go I had to turn it off after a couple of days.
I have written my own honeypots to reduce the false positive rate. I simply have things like a VM with RDP and SSH open to the internet and any IP that tries to login gets banned at the firewall for x days. It works really well.
