I have a telegram bot that for any received message runs a program in the server and sends its result back. But there is a problem! If a user sends too many messages to my bot(spamming), it will make server so busy!
Is there any way to block the people whom send more than 5 messages in a second and don’t receive their messages anymore? (using telegram api!!)

Firstly I have to say that Telegram Bot API does not have such a capability itself, Therefore you will need to implement it on your own and all you need to do is:
Every time the bot receives a message it must run a database query to see that the sender’s chatID exists in the Black_List table or not. If it exists it should continue its own job and ignore the message(Or even it can send an alert to the user saying: “You’re blocked.” which I think can be time consuming).
Note that as I know the current telegram bot API doesn’t have the feature to stop receiving messages but as I mentioned above you can ignore the messages from spammers.
I have achieved it by this mean:
With these to functions above, you can record how many messages sent by any user in the period. If a user’s messages sent more than expected, he would be restricted.
Then, every handler you called should call these two functions:
I’m using
pyTelegramBotAPI
this module to handle.I know I’m late to the party, but here is another simple solution that doesn’t use a Db:
Create a ConversationState class to attach to each telegram Id when they start to chat with the bot
Then add a LastMessage DateTime variable to the ConversationState class
Now every time you receive a message check if enought time has passed from the LasteMessage DateTime, if not enought time has passed answer with a warning message.
You can also implement a timer that deletes the conversation state class if you are worried about performance.
