Is it possible to somehow use bots to your advantage?

Question

Search Engine Optimization

Good afternoon. I constantly encounter mass registrations on my site, despite all kinds of captchas and more.
In general, sometimes sometimes at the registration address, for a day it comes from 2 to 5k uniques.
The analysis confirmed that these are live users, perhaps they are registered for a penny, from various services that provide such tasks.
I wondered, while simultaneously working on the elimination of these bots, is it possible to play a plus on this?
Since users are alive, is it possible to give / transfer / page weight, anchors or some texts (of my subject) to the main page? Or any other?
Registration/Personal account/ excluded from the index, as it is not needed, while there are direct visits from bots, and a very low percentage of failures.
Might be stupid but interesting.

Answer 1

The PS knows perfectly well what kind of users they are - even if they are alive.
Pessimization for cheating has not been canceled ...
