A triangle icon started appearing in playlists against users who didn't own the Black Ops Pass. A lot of people think the inclusion was there to 'shame' users who don't own it whilst Treyarch have claimed it was merely 'a bug'. The issue is now fixed apparently.
I'd probably be more shamed actually owning the pass and looking at the lobbies below, a larger portion don't compared to those that do own it. In the past, users would write something this off as just a bug but the amount of these 'bugs' this game has had along with the relentless bullshittery of Activision; it wouldn't surprise me if it was a deliberate psychological implementation gone bad. People don't seem to trust Treyarch like they used to either.
You be the judge...
