Why are my topics getting removed?

Is it mods not liking what i say?
or is it just because they get automatically removed when enough people report them no matter the reason?

I see people creating useless topics about them leaving and just flooding the forums but when i try to start an actual discussion it gets removed?
am i doing this wrong?

I usually create a title, fill the post then chose category and then click the create topic button. Am i missing a step?

even better it confirms that i created a post and i can see it in my activities until it disappears from existence a few minutes later without even a message saying it got removed? i guess or whatever happened to it

there’s a posibility it got merged with another of the same subject?

would that give me a warning if it happened?
i literally received nothing when that happens (happened to me twice so far)
