Came from 14 different instances - many of them major. Of those instances, the instance with the most votes contributed was lemmy.world (i.e. your own instance), from which my instance has seen 14 votes for that comment.
Of the voters, I looked at the distribution of the person IDs assigned on my instance, which approximately represents the order they were seen by my instance (e.g. they voted on or interacted with another comment). If there was vote manipulation, I’d expect to see lots of IDs close together. However, there are not runs of IDs that are close together. To avoid this when manipulating votes, they’d need to have planned in advance, and made accounts and used them individually over time before finally deploying them to downvote you.
If there are instances that are a significant source of vote manipulation, and the local admins are unwilling to address it, there are options available to instance admins like defederation.
However - in the case of your comments, there is no meaningful evidence of vote manipulation.
