Can we add an account age restriction for comment/posts on this subreddit?

I am spammed multiple times a week by bots due to my activity on this subreddit. Every time it is the same: Some BS coin/token offering where the script creates accounts and then goes through posts/comments in this sub and responding. A common trait is the accounts are all brand new. They create them and start spamming immediately. A simple restriction on age of account would prevent this spamming.
