With this script, can you get the list of subcribers ?

I don’t think the Lemmy API exposes the subscriber list of a community, you’ll need access to the instance database.

What I did was checking every post for the last 365 days for user activity and store every user that have interacted with the community.

lemmy_session and lemmy_references are the same as for the LiveThreadBot (inside the src folder): https://gitlab.com/UlrikHD/lemmy-match-thread-bot

get_posts() may be missing from the lemmy_session.py file though

    def get_posts(self, *, community: int | str | LemmyCommunity, sort: str = 'New', page: int = 1) -> dict[str, any]:
        """ Gets the posts of a community.

        :param community: The ID of the community to get the posts of, can also be a LemmyCommunity parseable
        string/object.
        :param sort: The sorting method of the posts, by default 'New'.
        :param page: The page number of the posts, by default 1.
        :return: The response JSON of the request as a dictionary.
        """
        if isinstance(community, LemmyCommunity) or isinstance(community, str):
            response: Final[requests.Response] = self.srv.get_posts(community_name=community, sort=sort, page=page,
                                                                    limit=50)
        else:
            response: Final[requests.Response] = self.srv.get_posts(community_id=community, sort=sort, page=page,
                                                                    limit=50)
        if response.status_code != 200:
            raise requests.exceptions.HTTPError(response.text)
        return response.json()

Excuse the ugly code, it was written as a one-off

and this part creates txt for easy copy pasting for tagging.

from json import load

    user_list: list[str] = load(file)

loop_count: int = len(', '.join(user_list)) // 9500 + 1
for i in range(loop_count):
    with open(f'reply_list_{i}.txt', 'w', encoding='utf-8') as file:
        print(len(' '.join(user_list[i * len(user_list) // loop_count:(i + 1) * len(user_list) // loop_count])))
        file.write(', '.join(user_list[i * len(user_list) // loop_count:(i + 1) * len(user_list) // loop_count]))

If you are referring FootballAutoMod it’s a very basic bot I wrote for posting weekly discussion threads. The tagging of people were just a simple script I wrote to get a list of everyone who have interacted with the community in the last 365 days and then splitting the list up to get within the 10k character limit for comments.
