Listen, if you, like me, think that spam is a problem, I have a simpler and cheaper suggestion than the one in the main thread:
We have a large volume of topics every day, always publishing the same works...
... My suggestion would be to create a new category, where authors could summarize the episodes of their stories; that way, they would post well-made summaries of the current episodes and would only publish their work again after releasing a new episode to summarize on the forum.
I have a thread that simulates exactly this, take a look please:
https://forums.tapas.io/t/summarize-the-first-chapter-of-your-story/84872
My idea is that everyone posts a summary of their story and puts a very catchy headline in the title space.
In the body, there will be relevant information, such as the type (novel or comic) and genres of the story, and, below, a summary of the episode in question, with the link to access the work.
Something crucial:
All responses in a summary post must be about the work being summarized; This will force other authors to make their own thread summarizing episodes.
I believe that this way, anyone who reads the summary and has been genuinely interested in reading the story will read it, and there will no longer be that flood of spam, as authors will only be able to promote their stories through summaries, and this will only be possible when new episodes come out, resulting in a cleaner and more objective forum.
I believe that just saying "read my story" does not generate interest, but giving details about it is very objective and, therefore, can arouse interest in the reader.
But of course, for this to work, it would be necessary to remove the promotion category, and then I don't know if you would agree with that :v
Well, I hope you will at least take this suggestion to your superiors, as I believe this tactic will reduce spam and bring objective promotions, as it explains what the story is about and, consequently, will arouse much more interest than promotional topics being spammed around.
