At the time of writing, it has -513.
Now usually, it would mean the round has some issues. But in this case, I don't think this is the reason. An announcement that has this many downvotes is usually accompanied by a lot of complaints in the comment section. Today we have none of that. Sure there are a few people who didn't like this or that, but there is no avalanche of negative comments that would usually accompany a -500 announcement. (So if you plan to reply to this blog with some complaint about the round — is it realistic that enough people downvoted it to get to -500 and nearly no one left a comment?)
Is someone botting?
