It has become apparent that @rodneyck@lemmy.world has been manipulating votes by voting with multiple accounts on other instances.

At the very least, on this post they have upvoted it using multiple accounts with the same username on different instances, as well as multiple votes in the comments of that post. It’s very likely they are doing the same on all their posts.

They are also harassing other users by digging up comments/posts then lying about them in order to slander the other person.

The comment chain on this thread shows this behavior:

(Note that there is an unmarked NSFW image from that user in the comments. This was used as an attempt to harass another user.)
