Your resident ghost Zolnir here, welcome, welcome to the land of d - oh wait, this is the interweb. Oh well.

As for idiotic comments, my only advice is to ignore them. At Youtube you have the power to report it - which probably isn't going to do anything, but hey, at least it blocks the comment from view physically - and for tumblr, well, I've only visited for art so it's literally a non-factor for me, not to mention I hate its format (stupidly small text, and in most cases complements horribly with the background).
