Stupid questions. Just kidding. I love to answer stupid questions because I enjoy telling the asker just how stupid they are.
I usually avoid questions with very long descriptions, especially when the asker did not separate the paragraphs, because I have the attention span of a chicken nugget and I am not willing to commit myself to reading all of it.
Oh, and questions with really bad spelling and/or improper grammar.
Usually genitalia questions, mostly How Do I Look questions unless they are seeking advice on make-up, new hairstyle or outfit. Some "heavier" topics I'd rather not get in to because it'll start a debate. I'd rather not, especially on the internet.
"Do I have a nice butt"? "Are my boobs too small"? "Am I ugly? People say I'm pretty but I don't know"? Questions with huge explanations And all the dick questions. There's more but these are the top annoying ones
