Hi. I follow mentions of my username in chat.stackexchange.com through an RSS feed, which is how I found this chat room. I believe it is public.

I also had a couple of my questions roomba’d away because of a downvote.

The thing about Web Apps SE is that there is only one active mod. So basically, the one active mod can unilaterally close/delete questions and answers without being checked by other mods.

Another example, this question: https://webapps.stackexchange.com/questions/166848/how-do-i-schedule-a-comment-on-reddit

It was unilaterally closed. I asked about its closure on Web Apps meta - https://webapps.meta.stackexchange.com/questions/4882/what-part-of-the-question-how-can-we-schedule-a-comment-on-reddit-needs-detai. Then, three users, including a (different) diamond mod, reopened it, but the same mod unilaterally closed it again just a few days ago.
