I got banned; doesn't matter still had [fun]

A few days ago, I saw a post on /r/AskReddit where the poster asked which sub has the most toxic community. I really didn't care about the answer but was happy to learn about new communities I didn't know anything about.

One of the posts mentioned /r/redditgetsdrawn which I had never heard of. Then I saw that people are providing pretty good drawings, you know - a few here and there, in between thousands of "good old college try" ones that don't look all that great.

So I thought to myself, this is something a bot can do. Take those drawings and add a pencil filter to it. ImageMagick has been a tool I've used before so I started.

Bot Code

import praw

import uuid
import urllib2
import os, sys
from imgurpython import ImgurClient
from subprocess import call
import time
def buildCommand(submission):
    # print data
    # Dont post if you have evenr posted here
    if hasPostedHere(submission):
        return

    # print submission.title
    submission.upvote # upvote the current post to be nice
    data = submission.url # get the url of a post and check to see if its a link to outside of reddit
    if "reddit" in data: 
        # print "reddit link"
        return

    comment = "Hello, I'm a bot written by ichillax. In the event that my human counterparts can't generate anything that you'd like, I would like to gift you my own drawing <3\n\n"

    response = urllib2.urlopen(data)
    # Save the file 
    with open('workfile', 'wb') as f:
        f.write(response.read())
    # Check to see if the file is an image file and rename it properly if it is
    if imghdr.what('workfile') != None:
        newFileName = str(uuid.uuid1())+"."+imghdr.what('workfile')
        os.rename('workfile', newFileName)
        # Turn the file into a sketch
        runCommand(newFileName)
        # Upload the file to imgur
        imagurPath = client.upload_from_path("prime_"+newFileName, config=None, anon=True)['link']
        # delete the file locally from the machine
        os.remove(newFileName)
        os.remove("prime_"+newFileName)
        # add the image to comment text
        comment += imagurPath
        # print "uploaded", imagurPath
        print "Commented", submission.title
        submission.add_comment(comment)

    else:
        os.remove('workfile')

def runCommand(filePath):
    #print "Drawing..."
    os.system("./Draw.sh "+filePath)
    # print "Done drawing"

def hasPostedHere(submission):
    submission.replace_more_comments(limit=None, threshold=0)
    flat_comments = praw.helpers.flatten_tree(submission.comments)
    for comment in flat_comments:
        if str(comment.author) == str(BOT_USER_NAME):
            print "Already commented here"
            return True
    return False
