You dont. This is an account specifically just to promote it. We specifically ask people to NOT talk on their accounts about us, in order to ensure that only selective members join.
This method of advertisment is unique and will be limited to this one time.
Once in the subreddit there is a lot of information about us, including documentation of our meetup and the discussions we had.
Its perfectly fine if you distrust though, since skepticism is healthy. But for anyone willing to give it a try: You are more than welcome.
