I wasn't so much worried about the pseudonym use as putting up garbage test content. Greeking, for example. Is there a danger of losing my access for noncompliance with their user agreements since it's not in the spirit of the platform, for example. I couldn't find anything in their fineprint that was super clear about this.
That's why I use pseudonyms just in case I publish something I thought was fab turned out not quite that great. Plus the way everyone burns everyone just because they think there's something 'problematic' about your piece who wants to risk their identity being labeled RACIST over something that only an opinion. You're two years of sweat, hard work and money could be trash-binned over a viral tweet.
In the past they had issues with people trying to cheat their system to gain more money by "stuffing" books with nonsense. They crack down on that a lot, if that's what you mean. You can put up shorts though, 1500 word short story for instance would be perfectly acceptable.
Yeah, this is kinda where I'm waffling. On the one hand, I don't want to trigger Amazon's shenanigans detector and get myself banned from the platform; but on the other hand, I don't want to spoil first publishing rights on legit IP. I think I will play it safe and publish legit but otherwise unsellable IP as a practice book, under a throwaway pseudonym. Well, maybe not throwaway, it could be a permanent platform test profile for later projects maybe. I do have a ton of flash fiction.
I still feel pretty bad about this, even though I mostly removed all the foot print. It was a weak move to put up a book without it being as good as it could have been, but even weaker to then go back on that decision and remove it. I should have just left it and let it be what it was.
I think a lot of us have done this so I wouldn't be too hard on yourself. I know for a fact there are bestseller authors on Amazon (their books have made the top 5 in the Amazon store) that have an entire collection of full length novels that they've unpublished for various reasons, including the writing quality. And those same authors even have had books taken down by Amazon because too many readers submitted grammar edits via some strange kindle app ability and it became a "customer quality issue". Now they sit on their kdp dashboard waiting for a re-edit.
