I read before (but a mod could confirm) that the automatic rules to prevent duplicate posts are purposefully loosely set. There is some rule to not post the exact same link, but a small, meaningless variation at the URL is allowed as a trick to posting duplicates.

It is a practical way to give second chances without giving too much room for spamming. The fact that you didn't even know it was allowed seems to prove that it works.

What is not ok is to delete your own former posts to pretend you are posting for the first time.

With this perception in mind, my own personal rule is if my first post does not get too much traction, I post a second time, 10~12 hours later (to get a different audience). Usually, I stop, sometimes when I am too optimistic I post a third time a couple of days later. And then I give up and stop posting.

You can clearly see this pattern in my submission history.
