I want to know how to block bots from accessing my server?

I am getting many bot IP's in DHT or they are connecting to me from all over the world so IP block bans don't work.

The main bot I am having issues with is called "BM 0.0.0.1"

How do I block a peer with a client named "BM 0.0.0.1" or a Peer ID that starts with "-BM"??

It appears that this bot is trying to overflow a buffer.

I am trying to ignore them, but there are so many it is difficult!!!

FYI... The status code the bot is creating is called "metadata request overflow"

Is there a way to block misbehaving clients?

check out settings-transfers-files

Client Filter
This will open a window that lets you full configure the client filters that are applied to all transfers.  You can filter peers based on Client ID or their unique Peer ID.  Allows for whitelist / blacklist / exemption rules.

can you post screenshot in postimages.org and teach me how to identify such malicious peers?
