Is my account shadowbanned??

I created this account about 3 days ago to actually start using Reddit. I've been commenting to build up karma, made a few posts, and barely managed to scrape together 10 karma.

But I just logged in, and my profile picture is completely gone. On top of that, all my posts got removed by Reddit's filters. Why is this happening? It's honestly driving me crazy. I have zero clue how I'm even supposed to use this platform if this keeps happening.

Is there any way to fix this?
