You have not explained why your post had to be “independent”. Perhaps there are reasons—maybe good ones—why you wanted your first appearance here to be its posting, but I don’t see any reason why it’s better for LW for that to be so.
In any case, “X has a cost” is not a good argument against X; there can be benefits that outweigh the costs. I hope you will not be offended, but I personally am quite happy for you to be slightly inconvenienced if the alternative is having LW deluged with posts from spammers.
No one’s requiring you to make “shit posts”.
