Telegram Bot Error Code BOT_BLOCKED_BY_USER: How to Fix It

Q: Can I still send messages to a user who blocked my bot?

No, when a user blocks your bot, Telegram prevents all message delivery to that user. Attempting to send messages will result in the BOT_BLOCKED_BY_USER error.

Q: How do I know if a user has unblocked my bot?

Users who unblock your bot will be able to send messages again. Implement a message handler that reactivates blocked users when they send any message to your bot.

Q: Will the BOT_BLOCKED_BY_USER error crash my bot?

Only if you don't handle it properly. Implement try-catch blocks around your message sending functions to gracefully handle this error without crashing your bot.

Q: Can I prevent users from blocking my bot?

No, users have the right to block any bot on Telegram. Focus on creating valuable, non-spammy content to reduce the likelihood of users blocking your bot.

Q: Should I remove blocked users from my database?

It's better to mark them as inactive rather than delete them. This preserves user data and allows for easy reactivation if they unblock your bot later.

Abstract

The BOT_BLOCKED_BY_USER error occurs when a Telegram user has blocked your bot, preventing it from sending messages to that user. This is a normal part of bot operation and requires proper error handling in your bot's code.
