Until they invoke their right to erasure
The GDPR does not have the ability to mandate my personal behavior, and even if it thought it did, many of us turn out not to live in Europe.
What are they going to do, prevent my text file from doing business in France?
Besides, you're saying "just target them," but you don't actually have the ability. Nothing you can do will get those lists taken down, even if you're on them.
Wrong.
The key understanding is that silly people do not, here, include courts and law enforcement.
The thing the poster is trying to reference is the GDPR, and the GDPR does not offer this right with regard to other individuals.
What makes this silly is people pretending rights exist that actually do not.
