Harriet Tubman appears here as a test rather than as an inspirational quote. Anna Wright asks whether you would have half that woman's nerve, and she means it as a question about you rather than as a compliment to history.
Her post on spam is short and unambiguous. Filling other people's feeds and inboxes with your link marks you as somebody with nothing to offer, and she does not soften that with a workaround.
The copywriting posts justify a visit on their own. Writing that sells is a learnable skill, the way to improve at it is to keep writing, and she points at specific places to learn rather than describing the benefits and stopping there. If your solo ads go out and nothing converts, this is the post to read.
She writes about a reality dating show with clear enjoyment as well, and makes no attempt to fit it in with anything else.
Start with the copywriting post, then take the Tubman one when you want something less comfortable.
