Someone said earlier in this thread that they changed their rules 2 years ago. So yes...that is probably the case.
Now they are mostly bullying new comers.
It was me.
I left the site in the wake of the Google contract that enforced this.
There are stories like Seaspecter's which are "legacy" (it's not the term what Moderator John would use, but it is what they are).
The "legacy" rules predate the draconic rules enforced by Google's contract.
Considering how their algorithm work, it is extremely unlikely for the "legacy" story to raise to the top and thus be displayed by the site. It's not entirely impossible, but it is very unlikely, hence advertisers wouldn't perceive any problem with their advertisement being associated with the wrong content. Your story, on the other hand, is new, and the moderation works harder to restrict any content the advertisers may not like. If you manage to pass the "cover inspection" there is a good chance than any of your chapter could be simply deleted to not offend the advertisement. All advertisements on their mobile ap is un-skippable and intrusive, not to mention it could access even your contacts or even the photos, so it is a little spyware too (courtesy of Google)
Keep in mind that most "censorship" on site is not conscious, the moderators are mostly absentee, it is entirely automatic 90% of time. Your busty girl rang the same alarm of the in-built software (once again, courtesy of Google) and alerted the moderation.
However, the story of being "legacy" doesn't exempt them from rules, they are simply buried by algorithm. If it has a warning, i.e. "sexual content warning" (not actual content) it is already rendered invisible by default, hidden behind age verification which in case of application is your ID (the webpage accessed through computer bypassed it, at least by the time I was gone).
