Upon browsing very old threads and marketplace deals way back when this forum is launched. I've seen this first time in this forum, I never know that there is an option before to be anonymous as is. 

I know that it's remove for various reasons and I speculate that it's removed due to inefficiency and to avoid outlaw post in this forum.
Will you agree if such feature were brought back to this forum?

I can see first time visitors, People who just have questions about his situation on crypto that don't want to create an account will be the one utilizing it. Instead of creating account for such single use and leaving it, They can use this anonymous feature.

I'm sure that this could be problematic since it attract spams in the forum but restricting them to post only into a newly created board such as [Anonymous posts](I imagine and invented the name) will sorta filter all those anonymous posts.
