Last time I checked I was Susanna--So why does the meme say I'm Snape?

Mmm, I am Lemon Flavoured. I am bitter and twisted. Expect from me acerbic humour and sharp commentary. While I may seem nasty at first, I'm actually quite good company if I like you, so long as you don't mind a bit of cutting to the chase. What Flavour Are You?

Shocked

I'm a bit tired today, because I had a not-so-good night, and therefore can't do much more than read, partly books, partly fan fiction. That's always a good opportunity for finding a nice badfic. I'd found this which is quite weird and was just about to copy the URL, when I saw that it had got one review. Curious as always, I read it.
And was totally, totally shocked:

Miaou your story totally sucks and so do you you bloody american you stink and so doz your prez. You are all gonna die when UK will declare war to USA and all of you filthy american assholes are gonna join your ancestors to hell and I'll spit on your grave and burn your body and kill your momma and your dad. Miaou quit writing stories, there are enough problems on earth like that. If you dare update this story, I'll localize you and hunt you and I won't rest till I've seen your corpse. Fuck USA!

Written by an anonymous reviewer called Pussycat.
Is there anything ff.net can do about this kind of troll, if they post anonymously? Is there a point in telling them about the review?
