She seems to have done this as a political statement on gender, which I personally support on its face but I do hope this doesn't have an adverse impact on students who once relied on her videos. She used to offer her videos as torrent downloads for easy teacher access -- I wish she'd left her website up to have the videos still accessible to those in need of them off of YouTube.<p>Other maths YouTubers will take her place and already have as she has not been that active in recent years anyway.<p>That being said, one thing is that I'm <i>certain</i> of is that she did not remove her videos due to online harassment, because this is something she's spoken about many times before. In her video "Feeling sad about tragedy" (the video I'm most mourning from this recent purge) she spoke about this topic over a visual of scrolling through a Gmail search of "marry me", showing off 100s of incels who had messaged her via the comments section inappropriately. I don't want to paraphrase everything she said, as this video is likely in the Internet Archive for you to see, but the quote that has stuck with me all these years is <i>"Why would I be worried about what I get on the internet as Vi Hart when it's nothing compared to what I get in real life as me?"</i> She also had a video about comments specifically, "Vi Hart's guide to comments", where she spoke about types of online comment abuse and the reasons not to respond to any of it. She ends by saying "I, Vi Hart, am... not scared at all."
