Many tasks are getting way more upvotes than I purchased (not organic)

On many of my tasks, I choose the rank comment button, which may suggest something like six upvotes, and I'll end up getting 15 to 20 plus after a day or two.

This ends up looking very suspicious when the post only has a handful of upvotes in the top comment only has four to five upvotes.

I’ve seen this happen on various different tasks
