The best part of the fediverse is that anyone can run their own server. The downside of this is that anyone can easily create hordes of fake accounts, as I will now demonstrate.
Fighting fake accounts is hard and most implementations do not currently have an effective way of filtering out fake accounts. I’m sure that the developers will step in if this becomes a bigger problem. Until then, remember that votes are just a number.
Yeah, 700 upvotes soon after a post is made could easily shoot it up to the top of even a popular sub for a few days (specially with the lack of mod tools rn), with others upvoting it purely because it already has alot of upvotes.
