If your comments annoy the other users, they have the choice to vote it down, after they are voted down, they are hidden so no one else will have to read it. It's not a matter of trolling, but preference.
That doesnt make any sense!
Saying"Oh she has a very cute top"or something else is annoying?!
IMO(in my opinion)I think its pretty disrespectful to downvote someones comment especially if it looks harmless.
And I think these downvote/upvote numbers are kind of effecting some of these peoples self esteem.
