No. People just say that so Tumblr wouldn't get overpopulated and people from their school wouldn't join. I think me telling you that breaks the "Tumblr rules" but it doesn't really matter anymore since everyone seems to be joining.
I suppose it's possible that any site can potentially have harmful material, whether or not it is intended by those running it. I haven't personally had any issues with Tumblr, though, and I use it quite frequently.
I highly doubt that because it's not something you download... if it did, then the website wouldn't have such a good reputation. I've never had any problems with Tumblr. :)
I have never had any problems with it but I have seen Connor post about it giving him viruses before lol
