Please leave. This website is not like Facebook where you connect with friends this is a place where your daughter or son can express their self without feeling judged. Somethings you may not want to see your kid post or talk about, this is why you shouldn’t have made a tumblr….
My dad has a tumblr, and I really enjoy being able to share the site with him. Whenever I find something interesting I can show him, and I can discover things I never knew about him through his blog posts and tumblr page. The difference is that my dad respects me and I respect him. He would never read a post I told him not to, and I give him the same decency. Saying that this website is only for kids, or not for people who happen to be parents is pretty against the non-judgemental, communal mindset we all try and enjoy.
Just saying.
