Are 2 Bonus Items Junk?

Because two guys got together and said to each other "Hehehe, let's screw with all these people by lying about equips going from 2 stats to 3 when cubing". It's obviously a rare random chance. Though I don't think it only happens during an upgrade, I could be wrong though.

For all you know, there is a chance that all this is an epic troll attempt, not necessarily involving the participants communicating with each other and/or agreeing on anything at all. It all just needs an idea, and a pioneer.
Though, I'm very much inclined to believe those three, thus my wish for concrete evidence. No accusations here, honestly.

EDIT: Much appreciated, Thorr, and good luck.
