We don't have bot filtering/blocking at the moment, but I can confirm that traffic filtering is one of our high priority features - https://roadmap.funnelflux.pro/

Note you can retrospectively delete data from certain IPs using the reset stats section.

If you are familiar with the IP addresses of the bots, you'll be able to look them up using Raw Events section - https://ui.funnelflux.pro/raw/hits

Hope this helps!
