Yeah, the false sense of security in combination with the fact that the Pre-Early Birds always seem to hang around "5 left" every day, sometimes they run out and then come back soon after (and the number of backers doesn't drop).

I've seen a few others comment about the same issue and then have their comment removed shortly after, it's not like not the campaign owner isn't present either, they just gloss over
