steem forever (rewarding old posts) with beem

What to do when you want to reward an old post with an upvote? There are services that are doing this as steem-forever but they charge some percentage for their service.

<p dir="auto">We need a script that creates a comment under the post, set the beneficiaries and upvote the comment.<br /> We are using beem: <pre><code>pip install beem <p dir="auto">for this. Store the following script as steem-forever.py <pre><code>#!/usr/bin/python from beem import Steem from beem.comment import Comment from datetime import datetime, timedelta import time import getpass import argparse def valid_age(post, hours=156): """ Checks if post is within last twelve hours before payout. """ if post.time_elapsed() > timedelta(hours=hours): return False return True if __name__ == "__main__": parser = argparse.ArgumentParser() parser.add_argument("authorperm") parser.add_argument("votepercentage") args = parser.parse_args() authorperm = args.authorperm votepercentage = float(args.votepercentage) wif = getpass.getpass(prompt='Enter your posting key.') stm = Steem(keys=[wif]) account = stm.wallet.getAccountFromPrivateKey(wif) c = Comment(authorperm, steem_instance=stm) if c.is_pending() and valid_age(c): while c.time_elapsed() < timedelta(seconds = 60 * 15): print("waiting that the post is 15 minute old") time.sleep(60) c.upvote(weight=votepercentage, voter=account) else: body = "The reward of this comment goes 100 %% to the author %s. This is done by setting the beneficiaries of this comment to 100 %%." % (c["author"]) beneficiaries = [{"account": c["author"], "weight": 10000}] stm.post("rewarding %s" % c["author"], body, author=account, reply_identifier=c["authorperm"], beneficiaries=beneficiaries) c.refresh() c_comment = None created = None for r in c.get_all_replies(): if r["author"] == account: if created is None: created = r["created"] c_comment = r elif created < r["created"]: created = r["created"] c_comment = r while c_comment.time_elapsed() < timedelta(seconds = 60 * 15): print("waiting that the comment is 15 minute old") time.sleep(60) c_comment.upvote(weight=votepercentage, voter=account) print("Comment upvoted") <p dir="auto">When running this script, it asks for the posting key. This key is only temporarly stored in the steem object and will be forgotten when the program exits. <h2>Rewarding a paid out post <p dir="auto"><span>I selected an old post from fullnodeupdate and will reward it with my test account <a href="/@beembot">@beembot with a 50% upvote: <pre><code>python steem-foreever.py https://steemit.com/full-nodes/@fullnodeupdate/full-api-node-update---25102018 50 <p dir="auto">A new comment is created and after 15 minutes in a loop the comment is upvoted with 50 %.<br /> <img src="https://images.hive.blog/768x0/https://ipfs.busy.org/ipfs/QmabsaZb6Ka6H1SwLcuak5RjAYnvpnNJNH5tCqaDy7wdhT" alt="image.png" srcset="https://images.hive.blog/768x0/https://ipfs.busy.org/ipfs/QmabsaZb6Ka6H1SwLcuak5RjAYnvpnNJNH5tCqaDy7wdhT 1x, https://images.hive.blog/1536x0/https://ipfs.busy.org/ipfs/QmabsaZb6Ka6H1SwLcuak5RjAYnvpnNJNH5tCqaDy7wdhT 2x" /><br /> The beneficiaries are set to 100 % for giving the complete comment reward to the author.<br /> <img src="https://images.hive.blog/768x0/https://ipfs.busy.org/ipfs/QmNTH6jV5r5mLzyAmUKupvWobVkEpqXpwKKiCCnkdWvYjj" alt="image.png" srcset="https://images.hive.blog/768x0/https://ipfs.busy.org/ipfs/QmNTH6jV5r5mLzyAmUKupvWobVkEpqXpwKKiCCnkdWvYjj 1x, https://images.hive.blog/1536x0/https://ipfs.busy.org/ipfs/QmNTH6jV5r5mLzyAmUKupvWobVkEpqXpwKKiCCnkdWvYjj 2x" />
