warsame95,
Something that has really helped me is to think of it from Ebay's perspective (with the use of metaphors  ).
1. They don't want to have an online market full of ⊗⊗⊗⊗ items and sellers, but at the same they are much more concerned with making as much money as they can. Regardless of whether a seller makes $50 selling chinese ⊗⊗⊗⊗, or perfectly authentic items, ebay still gets their %.
Think of it like the drug war in the US. If you come into the game like you want to be the next Escobar, you're gonna get popped real quick. But if you start off dealing slow, and maybe even do some legit work on the side as a front for the real cash flow, you fly right under the radar.
2. When your account is limited/suspended/not what you want it to be, it is NOT "you vs. eBay," instead its "you vs. some person on the phone/computer." In order for an improvement to be made to your account status you need to think how sketchy your account would look if someone looked it over (especially in the first 21 days)
A tip here is to consider who this person probably is. I'm no mind reader, but we can be certain that this person does not care a thing about ebay. Think about any job you have had. Did you do everything in your power to help benefit your employer's business? No, you probably did that absolute minimum required to keep the job and get paid. So, from this we learn that whoever is working for ebay and reviewing your account is probably not going through every little detail like and IRS agent, but instead is probably giving one quick glance to see that nothing looks weird/out of place like an account with 5 feedback, and 5 sales of something sketchy (something sketchy = anything you find on the internet and can sell for more than 200% profits)
Basically, when I look at my seller account I want to be able to feel like my account looks good just by looking at the quick indicators like DSR's and my more recent feedback. My theory is that if my seller account looks clean on the surface level, I can get the person reviewing my account comfortable enough so that they don't feel like they need to dig any deeper.
