There's lot's of reasons for square to not reply to threads. If it's a thread about a wanted feature, the best case scenario response is going to be, "We'll look into it" otherwise they're not going to respond because they don't want the feature for whatever reason, they're already working on the feature or the feature isn't possible. Likewise they're not going to go "Yea this is a great idea, we'll get right on it," because promising a feature and then finding out it that it isn't possible for whatever reason is a sure way to build distrust and disappoint the community.

Likewise you'll never ever get a response from square about rmt outside of the reports that the post weekly (The latest one being found here!) because they're not going to detail their process of catching and punishing rmt in any public place or even outside of the office that it's dealt with, nor should they. You don't catch people by telling them exactly how you plan to catch them so they know exactly how to skirt around it and continue operations care free. This also doesn't mean that square is ignoring community suggestions but they're never going to pop in and say "yea these are great, we're going to use a few of these" for the same reason.
