The OP technique will help you in this case because it's not worth to reply ad hominem attacks. It's a waste of time and sats, both are limited and scarce, so skip these kinds of comments and keep doing what you do bro.

Why would you bother to reply something like that? Well, let's say you want to, that's fine. The next day, you will check your stats and see that you paid with your time and money to reply something that doesn't have any value other than follow the path of someone who doesn't even care about your comment, just made there to insult you.
