Excluding certain authors from frontpage

I’d like to prevent certain authors from posting to the frontpage of the site.

Using 2.3.1

Tried using a category plugin which allows only certain user levels to post to a specific category and another plugin that only allows a specific category to be posted to the frontpage.

But it seems all the plugins out there cause database errors with my site and don’t work.

Do you have any ideas how I can allow certain authors or certain roles under role manager to post only to the 2nd page of the site?

Thanks for your help.
