I don't think it would be possible to stop a certain number of characters because messenger has to first receive the whole message to trigger the message received event. The script above blocks them after a couple of messages in x seconds because by the time the script can block the user, you would alreadt have received the message, whether it was displayed or not. Thats why it would be no good to just replace a message with max. characters with an empty string or a warning message, because you would still have to receive the message they sent in the first place. Also, what if thwere was a legitimate reason for them sending a message with max. characters? How would you be able to distinguish it?
