(Question) Is it a shadowban?

I tested my account for a shadowban using a web tool, I also checked with another account / in incognito mode that my posts show on hashtags.
There's just one thing that's not right: when I'm logged in I see my pics reaching top post on hashtags but when I check it in incognito or with another account I can't see them in top posts anymore.

Have you heard of this? Is it permanent?

what tool did you use to test ur acc for a shadowban?

i can't add links to my post yet but it's the first thing in google when you type "shadowban test"

strange thing is that i kept testing the top posts and sometimes i see my pics in top posts both from my account and in incognito mode and sometimes i see them only from my account.
