Site shadow-banned on Reddit?

Quick description of the situation:

they removed my thread on one of the subreddits (big one) and after that, submitting the site on that subreddit doesn't work - so I guess they banned/shadbanned me there.

However, it seems it is Reddit-wide ban as the submission of link to my site is not showing up on any subreddit. I even tried submitting to one subreddit I am moderating (with my other accs) - not showing up.

But the weird thing is: I get no email to my moderator accounts that the site is caught in spam. So, it doesn't appear anywhere. Is this completely banned domain? Any hope I get it back?

I just had a look for the subreddit that you site gets banished to, I can't remember the name of it,
but its like a sub run by a bot that moderators submit your site to, and leave a comment,
you can always message a mod if you find it, tell them you are a beautiful blonde, who thinks someone has played a prank on your site,
and could they remove it for a $50 bill?

you mean r/shadowbanned?

If the site is shadowbanned (and it does happen especially with low-quality websites), then no amount of doing anything is bringing it back. Time to get a new domain.

May be your domain is Banned in reddit bro

I don’t think so. Reddit is not Instagram, but who knows.

so what is the solution if domain got shadowbanned or banned? buying new domain and redirecting to old one?
