I posted to r/help…nothing. just a singular upvote from somebody.

I’m here because I thought this sub had a nice amount of users on a it good chunk of the time.

My problem: My posts are not showing up on my subreddit. They show up on my profile. I posted again around 3 hours after the first two posts that showed up on the sub. That post showed up.

Is there a cool down to posting? Why is there a cool down in my own sub?
How can I post without a cooldown?
