Update: Eventually I was able to get in using Chrome or Firefox. Their hashrate was much faster than Pale Moon. Still can’t use lemmy.ml in Pale Moon.

I tested some other instances that are behind Anubis: quokk.au, lemmy.ca, lemmy.nz. The difficulty levels they assigned me were 1, 3, 4 respectively and I was able to get in after a few seconds. dbzero uses haphash and their challnge took my browser 566 ms.

No VPN. ISP is Comcast in USA. My OS is Windows 7, not sure if it considers that to be shady. Was using “Pale Moon” web browser at first. Then I tried in different browsers and had similar results in Chrome and Firefox.
