What is top members and how do I remove it?

Version 7.2.1

The member block that you can put on the home page has links for latest, top, and online. What is top? Is that based on the rating system? If I have profile rating turned off in advanced settings, why is that even an option?

Where in the code should I fix this?

It has to do with profile votes. 
When a member gets four or more likes they start showing up.

You can change the settings, at least you could in 7.0.x, not sure about 7.2 and up.

It was discussed years ago; I'll see if I can locate the post(s.) 

I don't want people to vote on profiles. There is a setting in Advanced Settings > Profiles to disable profile rating. This removed the voting block from all profile pages. But top still appears as an option in the drop down.

I guess I am going to have to edit that drop-down in code. I was wondering if anyone knew where or if I have to go digging.

In templates\base\scripts\BxBaseIndexPageView.php

Find :

       $aModes = array('last', 'top', 'online');

Replace with :

     $aModes = array('last', 'online');
