Why are there so many messages? +If you are a member of a normal group (non-supergroup), all messages sent to +that group are being copied to your personal messages at Telegram's servers. + +If you later leave this group, those messages are being deleted at Telegram, +but since all messages are continuously numbered, you can't simply delete +them because that would leave a hole in your message numbers.
