My reddit bot replies to same comment and itself over and over

So, I am very new to python and made a simple reddit bot which replies to a comment. It worked fine this morning, but now it replies to the same comment and even itself over and over again. I can't find how to fix this with my poor googling skills... so, here I am. The code is this

import praw
import time
import config

REPLY_MESSAGE = "Di Molto indeed"

def authenticate():
    print("Authenticating...")
    reddit = praw.Reddit(client_id = config.client_id,
                    client_secret = config.client_secret,
                    username = config.username,
                    password = config.password,
                    user_agent = 'FuriousVanezianLad by /u/FuriousVanezianLad')
    print("Authenticated as {}".format(reddit.user.me()))
    return reddit


def main():
    reddit = authenticate()
    while True:
            run_bot(reddit)


def run_bot(reddit):
    print("Obtaining 25 comments...")
    for comment in reddit.subreddit('test').comments(limit=25):
        if "Di Molto" in comment.body:
            print('String with "Di Molto" found in comment {}',format(comment.id))
            comment.reply(REPLY_MESSAGE)
            print("Replied to comment " + comment.id)

    print("Sleeping for 10 seconds...")
    time.sleep(10)


if __name__ == '__main__':
    try:
        main()
    except KeyboardInterrupt:
        print("Interrupted")

I took this code from Bboe's Updates to "How To Make A reddit Bot — Part One by Busterroni" I don't know what's wrong but it comments to itself. Sorry I know this a stupid question and it may be solved before but I couldn't find it...

Sorry again and Thanks in advance for helping!
