@Kind_Writer
Virtually everything in your post is incorrect, and I'm not saying this even slightly because I expect to be acknowledged as an "elder" or have my ego "stroked" or to "bully" you. Ironically, your post actually does the one thing that really annoys the legit writers who have been members of this forum for many years, and it's not really any different from what you'd find at just about any online forum community: namely, join a forum and immediately start dispensing your "advice," all of which happens to be either somewhat wrong or totally wrong and indicates to us that you don't have any experience in this field.
Try to convince the old-timers that though you are new to the fold, you will not come after their regular clients nor steal away any clients
You can't really "steal" anybody else's regular clients, simply because once clients find a good writer, they don't usually continue looking for writers on the forum. Most of them come here to find a writer for the first time or to find a better writer after the first service provider they tried failed to provide good work. Many of them never even bother registering or posting after registering; they just read posts and ads and contact writers.
Bowing to their superiority ... should help to thaw the ice.
This might have been true about one person who used to post here a lot, but it's not the case with the rest of us. If you just contribute to forum discussions in a meaningful way without dispensing bad advice, especially if you're as new to this industry as you are to the forum, nobody will have any problem with you. Don't try to make a big splash by posting 10 or 15 times in an transparently obvious attempt to reach the PM threshold and don't start bumping decade-old threads in that process and responding to OPs whose question or comment is a decade old as though anybody's been waiting around for your response since 2008.
However, some writers might have regular clients or a sizeable number of orders that could be shared with others.
If an established writer has any overflow, the last thing any of us would do would be to trust someone we don't know with a project. On the other end of the spectrum, if you're a fledgling writer, you don't have any projects to "share" with any other writer.
You need these people to help you get started, so antagonizing them is not the recommended way to go. However, that does not mean that you should accept getting bulled.
Nobody is interested in helping you get started because we're direct competitors for the same clients. However, most of us will interact with you very civilly and even provide advice about tangential matters that help you at no direct expense to us (as I just did in another thread in response to a new writer who asked about how to handle "vanishing" clients who owe money for delivered projects). Most of us will not help you learn how to find clients here, because we're direct competitors for their business; but that doesn't mean we'll be rude to you or consider you to be an enemy.
If you're a new writer who wants to be welcomed by veteran writers here, don't pretend that you have much more experience in this field than you really do; and ask questions instead of presuming to offer "advice" that you're not qualified to provide and that makes it very obvious to those of us who are that you really have no idea what you're talking about and that you're trying to pretend to be more experienced than you really are. That's not even a unique feature to this industry or this forum, either: go to practically any online forum, and whether it's about health, or law, or medicine, or physical fitness, or classic cars, or sports, or aviation, you'll find the exact same interpersonal dynamics between the most experienced members of those forums and its newest members. Ask questions and you'll almost always get good answers from the veterans; but come in dispensing your advice (especially bad advice that highlights your total lack of any experience in the field), and you'll get a very different kind of welcome from the veterans of
any online forum community, including this one.
