If you have a question directed at staff, you can also send in a help ticket here that goes directly to us. This board is more meant for general site questions that anyone can answer.
If you are asking if there are QOL updates made: yes. Just last year we got the dark theme after a dark mode had been requested for years, thats just the first one that comes to mind for me since I use the dark theme myself. The 'More inclusive items (Originally: POC friendly hair/items)' suggestion was also just fulfilled last month ^^ It is good to remember that we only have one site coder, Nick, who does any type of update not art related (ie new pets/items) completely on his own so sometimes it can take a while for these to be done.
I also did a quick search for your other question you mentioned, I assume you are referring to the one about deleting posts, and that system actually works as intended. Deleting posts is, for all intents and purposes, permanent, and unfortunately that can create issues if users are allowed to delete any of their own posts, no matter how old they are. One quick example I can think of is that sometimes users want to do things like delete their entire oekaki gallery, but they may have created art or characters for other people. Something that the user's who paid for it should at least have the chance to save or alerted it will be removed before it gets deleted permanently. Deleting threads would also delete other user's posts on that thread, which can cause issues or just general distress when their own posts are removed without their input at all (especially when there was no rule breaking involved). I could go into more detail, but the point is that it is intentional and we feels it works better if users report to us what they want deleted and so we can first review it and make sure it will not cause any problems before deleting something.
