If I was to give him an advice I'll say he should try engaging in the conversation he's replying to with his original thought and not try to prove some point everytime with his qouting of high ranked users.
Quoting others' posts is merit begging and relying on others' opinion. Really? Sometimes, if what poster needs is point out proof of rules or any rule explanation from admin, moderators, quote is enough. Sometimes, poster don't have to raise their opinion, quote is enough.
I follow some users because I can learn from them, from their posts. Sometimes, months ago, I did not bookmark their posts, so when I need (remembered read somewhere but don't know where to quote). Recent months, I've bookmarked good posts I see, and if quotes of such posts are helpful, why don't do this?
Sometimes, such quotes are more helpful than I write my own posts. How readers interpret those quotes (in right context, of course), it is their responsibility, not mine.
I'm not sure whats your motive for removing your signature? If you have been receiving criticism on updating your threads for a way to earn from your signature then I would just counter that by saying you post better posts than the majority of the others that are in the signature campaigns. If anyone deserves to be in a signature campaign you would probably be one of them because you are generating thousands of views on your threads and receiving merit for them which suggests that you not only post content that members enjoy reading but you are also exposing your signature to thousands of people which in terms of advertising is a good investment.
Manager contacted me why I left and confirmed I made good quality posts. As I wrote in OP, I just felt I need a break and refresh my mind.
I wish more people were like OP and could step away from this shitposting rat race, but some of those rats are unemployed and have families to feed and debts to pay.
My posts, sometimes are not high quality, but they are actually not shitposts.
Regarding to helpful posts, it depends on needs of readers. One high quality post is helpful for reader A (when that reader need that information/ solution), and is not helpful for reader B (when that reader don't need such information).
