Newbies are new students who should be willing to learn and not to teach.
I do not have any problem and do not see any problem if a newbie teaches me something that I didn't know. For example, let's say I don't know how to use the CPFP feature with my electrum wallet, and suddenly a newbie suggested to me the way I could do it, do you see anything wrong here? I joined this forum in 2022, but that does not mean I didn't know about Bitcoin before 2022.
So, What if I came to this forum and guided a legendary about how he should use a feature of Electrum wallet? Would you ignore my valid suggestions just because my forum rank is newbie? I have created a thread to discuss this thing a few weeks ago and a lot of people agreed with my point.
Newbies can help or teach other members if they have good knowledge on the issue.
The noise is from newbies who have yet learned enough knowledge but want to show off, with inaccurate knowledge. Their posts can mislead other newbies and other members at higher ranks. I would not say newbies must keep silent and only read but the noise if comes from threads that probably created by newbies to fish merit and contain many accuracy, will cause unwanted negative responses from forum members.
