I'm glad that it turned out that these previous results might have been inaccurate
(because the results were scary if found to be accurate)

I don't see how dir auths could blacklist specific client IP addresses
(tor clients use fallbackdirs)

can you let me know the start and end date of the scan (2018-03-12?) so I can check how many of
the relays you scanned (the top 100 relays by cw? at the time) 
had a tor version with anti ddos features at the time?

During your first scans (2017) there have  been no anti-dos features.

I'm excited to hear that.

stay under the public thresholds?

the consensus holds information about relays not about tor client IP addresses, but
I assume you know that and I misunderstood your question?
