マストドンで延々とリモートフォローをしつづけるやつです。

mastodon_remote_follow.rb

#!/usr/bin/env ruby

# how to use:
# 1. domains ファイルをこのスクリプトを同じディレクトリに配置し、リモートフォローしたいインスタンスのドメインを記載してください
#  (place `domains` file located same directory as the script file, and write the domain name of instance which you want to remote follow.)
# 2. run this script
# 3. 発見されたアカウントがあなたのインスタンスに登録されます, ただ、リモートアカウントとして登録されるだけで、実際にフォローなどは行われません
#  (new accounts might have registered to your insntance, but not yet `followed` by your account (only registered to instance as a remote account))
# 4. なんらかのお好きな方法でフォローしてください
#  (please follow them by your account yourself, your ways)
#  ex:  `curl -sS -w '%{http_code}' -H 'WRITE_YOUR_COOKIE' -H "authorization:Bearer xxx" -X POST https://mastdn.example.yokohama/api/v1/accounts/ID/follow`
