Have you cross checked the IP(s) of the bot? The User-Agent is easily spoofed, it might be some other bot just pertending to be a ahrefbot.
Regardless, as already mentioned can put handlers in your code to 'trap' bad actors. Check the useagent, and do something different. (can't totally block this way, but can minimise damage -make the requests very quick/short. And by not returning further links, stop them finding yet more pages to index). ... or use an external service to 'firewall' such requests - as already mentioned Cloudflare offer this.
