Should I Block Quantcastbot?

Probably not, especially if you benefit from an intelligence gathering service yourself. However, you might choose to block them if you're concerned about things like server resource usage.

How Do I Block Quantcastbot?

⚠️ Manual Robots.txt Edits Are Not Scalable
New agents are created every day. Instead, serve a continuously updating robots.txt that blocks new agents automatically.

You can block Quantcastbot or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
