Underscore in URL – SEO impact

Hi,

I’m using the Directory Theme Responsive. I came across a recommandation saying that we should avoid underscores in URLs as much as possible.

The recent listings located on the homepage gives underscores when browsing through pages.

Example:
https://www.redcastor.com/?home_paged=2

What do you all think? Should it be updated to remove the underscore?

Thanks,
