It comes down to what information we want users to know - if it's not really any of their business then we're not going to disclose any information about it. For example, knowing why another user was banned is nobody's business but the user in question and staff, which is why we don't comment on them. As for stuff such as upcoming events, collectibles, and restocks, where's the fun in it if we were to announce every 5 seconds what we were planning on doing for the next 5 months? Essentially we keep tight lipped on stuff that isn't in the interest of users until we are ready to publicly post about it. With the Pokeball, it's just like any other collectible - we've never really said in advance that a certain collectible is coming up (excluding ones in sets like flowers and birthstones, etc), most of the time we just post when they're released (clover, mushroom, party popper, etc), and that's that.
Basically if you're asking a question that has to do with the inside operations of how the staff work or do things, it's probably going to be ignored.
