Server ban option

I am getting added to some server even if i dont want to join. This servers use some bots that DM user the invite link and even if the users block them, They add the user in that server. they know if someone blocks them without watching the bot message, then they can auto-add users. And everyone does the same. So they make new bots and the bots dm the same user the link. Like they are 10-15 bots and 5 servers doingg this illegal thing. Please do something or add a feature where we can block a server and if blocked, we wont get in the server unless we unblock it. Thank you. My Discord- Begula#1248
