what do you do to gain trust/feedback?

[dimensteinss]

i feel like it's so hard to sell anything or obtain any way to gain feedback as a newcomer. advice? i'm trying to sell an almost maxed rs3 main but it just seems impossible so i think i wanted to get feedback more than just to sell the account but to actually be active here and be able to use that feedback to start something on here, where do i start?
