Good job! I'll give you a 7/10
That's a good effort, but you seem to have missed three things:
1) I ended a sentence with a preposition ("...to care with").
2) I used the word "affect" (which, when used as a noun, means a 'feeling or emotion') instead of the word "effect."
3) The post was dripping in sarcasm.
While the average troll may actually write like that (thus losing the implied sarcasm), few trolls actually call themselves such; the troll icon should have given it away, as should the direct reference to grammar Nazis.
Also, while it may have been poor form to refer to the writer as male, the name "Andy McAndy" [capitalization assumed] is usually male, and thus my assumption was a safe one. Good catch on the semicolon, however.
