I don't know about Tumblr (certainly not in my own social circle), but she had some mixture of clout and notoriety on Twitter (or used to be) and is attempting to continue her shtick on Bluesky, which is much less friendlier to it. She also has a podcast. I've actually mentioned her before and you also said then that you hadn't heard of her, so you may just be wisely erasing her takes from your mind, lol.
