Journal got blacklisted recently – how to withdraw the paper from the journal and database? Recently, the journal where my paper was published got blacklisted in a so-called blacklist. I was very surprised since the journal existed more than ten years.

My questions:


How to drop the paper from the indexing databases, such as Scopus. What will be the consequences and what are the procedures?
If I will keep the paper in this journal, how it will affect my academic career?
I don't think you can or should "drop" the paper.  To paraphrase the jewelry slogan, a publication is forever.  You can't take it back just because you don't like the direction the journal has gone, or how people's  opinions of the journal have shifted.  Also, from a legal perspective, it's likely you signed a contract giving the journal the perpetual (and possibly exclusive) right to distribute your paper, and you might also have transferred copyright; so you can't legally prevent them from keeping your paper.

And indexing services are telling the truth when they list your paper as published there; you can't prevent them from sharing that fact.

One could argue a moral exception for a "predatory" journal which actively misled you about its standards and practices, in which case one could say your consent to publish was fraudulently obtained.  Even in that case, though, I don't see what you can practically do, since the journal is unlikely to agree to drop your paper.

How it will affect your career is unknowable - it depends on how important this paper is to your career, the opinions of the people evaluating you, why the journal was blacklisted, etc.

I think all you can do is resolve to be more careful when choosing publication venues in the future.
