Don't know how much additional coding would have to go into a change like that, but if it's easy enough to do....why not do it?
There are newbies on this forum that only want to scam, you will see them manipulating just a thread, before you will know, they might create a moderated thread first, then later change it to self-moderated, scammers can use this as a new means to illicit their plans.
There are reported cases of some members' posts deletion by the self-moderated thread creators, even I have seen one or two of this complaints since I started posting on this forum. This will be worse if moderated threads can become self-moderated just as you commented too.
But one of the main good reasons this would not be good is when another member is not posting what the OP is expecting. Just like what has happened between tranthidung and I before. I am one of the members that like corrections on this forum which really helped me right from the start.
You can check this thread:
RBF vs CPFPtranthidung was right but also likely have another reason which is residing in him to be later making off-topic corrections which can not help me in anyway.
It is up to you.
My advice is what I learned, from my teachers, lecturers, and textbooks about Writing. If you have yet read any textbook for Writing skills, let's try to read one such book.
- 10 Amazing Books That Will Improve Your Writing Skills
- I did not read any of those books (simply searched and found them) but I shared because good books for Writing do mention what I told you.
- Did you know the saying "If you can't explain it simply, you don't understand it well enough"?
But, yet, I do not know when my post get bulky even up till now, especially my topics. I reported the post for deletion but modetor did not delete it. If I was able to convert that topic to self-moderated one, I would have edited his post and delete the part I quoted above and leave the rest without even thinking about it twice, but it will only be for my self-centered reason. Most or many people will misuse this, it will later result to people complaining about such deleted post while many can be useful, which will be a good reason moderated threads can not be a self-moderated ones because the harm will be more than the good. Some people will even only want to use it to harm some users that they do not just like on this forum when they are no more active/posting on this forum.
And as we know also that some people do not post in self-moderated threads which can still be because of good reasons.
