In any case, you should probably ask her directly by using https://rachelbythebay.com/contact/ (it might be wise to ask if you are blocked at all in the first place), I would think she would be happy to answer you there. Not sure about getting a response from her here on HN.

How are we supposed to know why some blogger blocked your IP? lol
