I am not interested in trading with people who are not trusted and i will definitely go first if some reputable person is interested in trading with me.
The issue is that you are looking for trusted members but you are a newbie. Meaning that you are not trusted like the members that you are looking for. So how do you expect trusted members to trust someone who is a newbie/ untrusted? Sounds (and it is) contradictory.
I know reputation on other platforms propably dont matter here, but:
-I can provide more than 90 vouches on my exchange discord
-I can provide 134 positive feedbacks (0 negative) on other forums, im even a middleman on one of them
As you said, none of the above matters here. Accounts in other platforms, reputation in any other site/ group/ channel/ forum, etc, doxs are useless.
Many solutions to secure the seller through PayPal? Like?
True. And who (besides yourself) will know from which bank account that money will come? Can be from almost anyone. Do you know that transferring "dirty" money is illegal, right? I'm not saying that it is but "no one" can know it.
