Ideally it should be, I guess. Maybe there is an admin setting to allow members to do that themself. I looked on a different forum where I am admin, but did not find it outright though. There are consideration why a community would only allow this via a request. Sometimes situations occur where people act out of emotion or spite, and do a disruptive account removal they later regret. In the case of SocialHub specifically the audience and public content focuses on open technologies and standards that are in the public’s interest and domain (generally speaking, not talking licenses). The intermediate step then offers time and opportunity to reasonably weigh what is the best option.
