They're all self moderated threads and I think chmod opens most of the threads in the press section. I guess he's cleaning things up. Nothing to do with bots or mods.
I'll chip in as well since 7/8 of my comments were deleted I'll have to clean my inbox spam later, that said seeing the trend above he is just cleaning up all commentary in the Press section in his self moderated topics, all that remain are his posts and quotes in which Chmod commented on one of the deleted posts.
