If you want to get technical Peon isn't either. This forum was around (and using Peon) since before WoW was even released... now Warcraft 3... yes.
Of course, but he is talking about his own status, and demanding sweeper instead of peon. But I will only advocate him if he is willing to take 'toilet cleaner'.
Jokes apart. Peon seems not a welcome name to a beginner on any board. Everyone starts with a single post.
So should it be administrator? moreover, it motivates them to be more active on the forum and remove this title as soon as possible.
No, SEO has nothing to do with visitors it is only for search engines. there are other marketing courses to handle humans.
Again, bounce rate optimization is not part of on-page SEO (and so is the speed optimization which also affects SERPs). But nevertheless, all marketing techniques go hand by hand to succeed in your efforts in them.
