Disable vim from auto indenting my comment lines, but continue to autoindent everything else

I want vim to stop auto indenting any time I add a # to the beginning of a link after its white space. Here is an example of the problem: Original text:

dog
    cat
        moose

If I add a # comment to the "cat" line, this automatically happens (Which I dont want): updated text:

dog
#cat
        moose

If I add a # comment to the "dog" line, this automatically happens (Which I dont want): updated text:

#dog
#cat
        moose

What I do want is the following, force vim to IGNORE any time I add a #, just don't indent, leave the line alone. Original text:

#dog
    #cat
        moose

Here is my vimrc currently.

set number 
set nowrap 
set linebreak 
set tabstop=4 
set softtabstop=4 
set shiftwidth=4 
set shiftround 
set expandtab 
set title
set mouse=a
set hlsearch
set smarttab
set autoindent
set background=dark
filetype indent on
set filetype=html
set smartindent
set nocompatible
syn on
set splitright

What I have tried: I have tried adding these settings with no success:

set nosmartindent 
set cindent 
set cinkeys-=0# 
set indentkeys-=0#

I also tried many of the suggestions in this post with no success. I like vim autoindent, I want vim to use autoindent, but NOT when I use a # at any time. How can I force vim to ingore applying an autoindent when # is used?
