How to get deleted users from channel (telethon)?

Question

In telegram when I click Subscribers it shows me about 50 last users and about 150-200 deleted users.

I tried this:

async for user in client.iter_participants(chat_id):
    if user.deleted:
        print(user)

This gives me only last 50 users and 6-8 deleted users. I need all 150-200 deleted users. How can I get them?

Answer 1

I solved this problem using GetParticipantsRequest with offset parameter somehow like this:

from telethon.tl.functions.channels import GetParticipantsRequest
from telethon.tl.types import ChannelParticipantsSearch

chat_id = -123456

offset = 0
while True:
    participants = await client(GetParticipantsRequest(
        channel=chat_id,
        filter=ChannelParticipantsSearch(''),
        offset=offset,
        limit=10000,
        hash=0
    ))

    deleted_users = []
    for user in participants:
        if user.deleted:
            deleted_users.append(user)

    if not deleted_users:
        break

    # doings with deleted_users
