I didn't get a chance to watch the video about the attacks before it was taken down, and I don't think I can watch the only video up for much the same reason.  She and her videos are priceless to this community imo.
I learned about vaping maybe a year or two before I actually tried one.  Initially, my research wasn't that great...obvious, unlikeable shills and deceptive, predatory web shops; I felt ashamed at the thought that I was just being scammed, and sad and angry that others in more desperate situations were too.
I can't remember what lead me to her videos a long while later, but they turned my view completely around.  Genuine, likable, funny, smart, and informative.  I found ECF, and I was overwhelmed with the depth and breadth of knowledge here, and with the kindness of the community.  Her videos and this community lead me to purchase my first PV, and I do not regret a single cent spent on it.
Even as cynical of the internet as I am, I was shocked that anyone could attack someone like Jan.  But now I think I could come up with a few people just scummy enough to do that.  Maybe it was just internet trolls.  Maybe it was anti-vape louses angry that vapers had someone so sweet to help newbies.  It makes me furious to think that this was a silencing campaign that succeeded.
I really hope she makes her videos public again, and maybe return to be an active and valuable member of the community.  Above all, I hope she does what's best for her, and I wish her all the happiness she deserves.
