The forum is filled with members, who have grown with experience and are ready to share good knowledge and information about bitcoin and cryptocurrencies to the younger members .however, I will advice any newbie who is been criticised to take it as a corrective measure and learn from his mistakes.
No. Do the opposite. If high-ranked members criticized you, do the same for them.

Criticize them for criticizing you.

Of course, I'm pretty much sarcastic with that one. Newbies must know the term "humility" especially when they're starting.
I don't know the last time I got criticized here when I'm still a newbie because of my posts. There might be some who criticized me but chose to ignore all of them. Sometimes, being criticized by other people will make us realize that we are doing something wrong hence, we are making some adjustments. For newbies, it's pretty normal to be criticized especially if we have limited knowledge yet.
As a newbie, don't stop to research. Trust me, I've been watching documentaries when I'm still a newbie, and what's the reason behind that? To learn more, and those learnings will be the ones that I'll try to share here.

Well, I'm still watching educational videos until now to learn even more.
