Actually the best is to ignore.

When you give time & energy you make the thing stronger.

So

Put time and energy into the things you want more of. And ignore what you want less of.

a lot of people talk smack about something they don't like. (they put time and energy into it) and guess what you are making it stronger.

Ignore it. its like not watering a plant it will die.

Long text but the idea is that you should put time & energy into what you want more of. And complwtely ignore what you want less of.
