How do I check if I’m banned on 4chan? Need help with 4chan check if banned process.

yo, anyone know how to 4chan check if banned? i think i might be shadowbanned or something cuz my posts aren’t showing up.

tried googling but all the guides are outdated or confusing af.

do i just make a new post and see if it appears? or is there a better way to 4chan check if banned?

also, does it matter if i’m using a vpn? kinda paranoid rn lol.

pls help a bro out, thx.
