Shadowbanned from a sub but not reddit itself?

Hi there. I'm somewhat a newbie in understanding the entire workings of reddit, but I rely on it often to get information for various things/to give information that I learn along the away.

I recently created this alt account instead of using my 4+ year account and officially joined a local sub to ask a question specific to my community and location. It immediately removed my post and told me I didn't have enough karma or age to my account which is wholly understandable. I took time, went and built up more karma, and returned to try to post again, and the same sub flagged me again saying I was unable to post.

Now, all of my comments in my local community sub don't show up and the mods of it say that reddit itself flagged me.

Is there a way to essentially "right" things in my community sub or do I have to start over? I don't remember getting an email from reddit to appeal anything.
