Hi,
a day without creating a bot, is a day lost :D
Today I would like to introduce a tool that allows you to vote on the comments of a particular user.
The need came from me, and I did not have such an alternative available on the "market", so I wrote myself for my own needs. (Or I'm not aware of :D )
The principle of operation is simple:
in settings.ini you set
[DEFAULT]
minPostLifeInMinutes = 5 <- miminal life of the comment
checkSecondsInterval = 5 <- every how long it should check the user's written comments
postingKey = xyz <- posting key for voter account
voterName = buddy <- the name of the voting account
weight = 100 <- voting power from 1 to 100
authorToVoteComment = grzegorz2047 <- whose account should check if a vote was made
I took out as many variables as possible that can be modified.
The bot can be fired up even on your local computer or any virtual private server with linux.
The requirements to run, are:
- python
- pip - access to a repository of python packages
- in the case of Linux, "screen" is also useful.
Once the requirements are met, the following command is executed to download the required libraries:
pip install -r requirements.txt
and then to run the script we call the command console command:
python index.py
The way bot works is pretty simple. When an author posts a comment somwhere, algorithm will look for last 20 comments and check if between 5-7 minutes there was any comment, if yes then like that comment. This can be used in any way you want or modify as you like :)
The source code of the script looks like this:

print("Vote cast successfully: " + str(broadcast_tx))
except Exception as e:
print('\n' + str(e) + '\nException encountered. Unable to vote')
def get_comments_to_vote(author, voter):
# 5 comments from selected author
q = Query(limit=20, start_author=author)
# get comments of selected account
comments = d.get_discussions('comments', q, limit=20)
minPostLifeInMinutes = int(config['DEFAULT']['minPostLifeInMinutes'])
maxMinutes = 7
now = datetime.now().astimezone()
commentsToVote = []
# print comment details for selected account
for comment in comments:
comment_created_time = comment['created']
diff = now - comment_created_time
minutes = divmod(diff.total_seconds(), 60)
minutes = minutes[0]
if minutes >= minPostLifeInMinutes and minutes < maxMinutes:
votes = comment['active_votes']
for vote in votes:
if vote['voter'] != voter:
commentsToVote.append(comment)
break
return commentsToVote
def main():
print("I'm on my duty, sir!")
commentsToVote = get_comments_to_vote(author, voter)
number_of_comments_to_vote = len(commentsToVote)
if number_of_comments_to_vote == 0:
print("No comments to vote")
else:
print(number_of_comments_to_vote)
for commentToVote in commentsToVote:
permlink = commentToVote['permlink']
vote(voter, author, permlink, weight)
checkSecondsInterval = int(config['DEFAULT']['checkSecondsInterval'])
schedule.every(checkSecondsInterval).seconds.do(main)
while True:
schedule.run_pending()
time.sleep(1)
All the files are available on github.
If you have any ideas for creating a useful tool (BOTH not too time consuming), I'd be happy to look at those ideas and try to implement it
