A bot detecting flair changes in r/PoliticalCompassMemes.

Both current and historical data are collected in a database. Whenever a flair change is noticed in a comment, the bot will answer said comment calling out the poster for changing their flair. This is not guaranteed, as certain circumstances must be met.

The bot will answer to every notable shift on the political compass it comes across. Any shift towards quadrants non-adjacent to the starting one or shifts towards the centrist quadrant are considerated notable.
For smaller shifts the bot will not respond, thoguh the data will always be collected.

Depending on the new flair chosen by the user, they'll receive a slightly different message. If they are among the top 10 flair changers they'll receive a custom message, letting everyone now their position on the leaderboard.

There is a 5 minutes anti spam delay for flair changes: if multiple changes occur during this time window only the first one will be answered (and saved in the database). Any further flair change will be discarded until 5 minutes have passed since the latest change saved in the database.

It's possible to summon the bot and inquire regarding an user's flair history. This is done by using the !flairs command. This command is available only on r/PoliticalCompassMemes.
Example: !flairs u/flairchange_bot.
There is a 2 minutes anti spam limit per user for the usage of this command. Errors such as: badly written Reddit usernames or usernames not present in the database will not trigger the anti spam timer.

The usernames of the top 50 flair changers of the subreddit are saved on the leaderboard. This reddit post is automatically updated every six hours starting each day at midnight UTC.

Whenever the bot comes across comments from unflaired users (users who didn't set any flair or chose to hide it from the community) there's a 10% chance it'll answer with a custom message. These messages are picked at random from a pool of insults or otherwise rude messages. See the Disclaimer further down this page.

The bot used to have an on-demand opt out feature at time of launch. User experience proved this feature to be not necessary, therefore it has been removed.

Some of the data gathered by the bot is available through the bot's official API.
