redbubbles authenticity

i actually have no proof or anyway to assure that posting on redbubble is safe for my copyright or even brand. like are they selling work and not relaying it to me? are they ghosting me on site and cancel culturing me forcing me to waste my time uploading new work i have no clue its also cos the shop is messy looking and not presented as fantastic landling page of wonderful items. its not. theyre hard to find and redbubble prioritizes the ugly looking listings like stickers and magnets over the attractive products like clocks and bags. whatever im sick of putting stuff up on that thing and not a single dollar came of it what a fucking waste of time i have anheadache thinking about how hopeful i was its so much fucking work running a small biz by yourself. its honestly not worth it financially. so its not worth it for me. i never got what i wanted out of anything in life.
