Telegram is a bot that allows you to pay for group subscriptions and for any goods/information you want to sell. It keeps all users in the database. It is convenient to use for a bad messaging.
After payment, the user makes a subscription, which is stored in the database, and after the deadline expires, the subscription is automatically deleted, and the bot banits the user in groups or channels.
