Again, it depends. Residential proxies are much more expensive, and most vulnerability scanners will never shift to them.

I believe that there is a low chance that a real customer behind this residential IP will come to your resource. If you do an EU service, there is no pain to block Asian IPs and vice-versa.

What is really important here is that most people block IPs on autopilot without seeing the distribution of their actions, and this really matters.
