Current settings allow anon posts ... But all posts require a mod's review and approval.
So don't focus on "who" just worry about "what" and "why" or "why not"...
If it becomes a problem - I'll keep this suggestion in mind... Currently I'd rather encourage more participants in this stream, rather than restricting access.
In an abundance of caution this image was reset to "NSFW". Let all Mods note that setting images "NSFW", where appropriate" is fully within their purview, and an expectation.
