So far, we don't really have to do anything because,
it doesn't mean that Feryl made these accounts to upvote his
own track, (one of the accounts created belongs to Ryan Gaylord though), but this could also be the results of "Hey friends, check this link out that i sent to a compo!" and then these three friends creates 3 accounts to upvote the track without any knowledge of the actual creator of the track (i've seen this before). so the only thing that will happen is that these accounts are trollified and scrubified.
