Keeping new posts by a specific username or userid from showing up in the 'New Posts'

[romeshomey]

I am trying to figure out how to keep the search.php from showing posts from a specified username or userid in the 'New Posts' area.

We are using the articlebot and if you don't log in for a long period of time, there are 1000's of posts from the NewsBots.

What I need is something so I can assign a group or certain usernames or userid's from being shown when someone goes to see the 'New Posts'.

I sat here for about 5 hours last night trying to figure it out but came up empty handed.

If anyone knows how I can do this, or may already have a hack that does this, please contact me via email or reply here.

Thanks guys.
