How to repeat the house sale information released by Gong Yisou the next day?

Hello, I'd like to ask how the house sale information released by Gong Yisou was repeated the next day. Gong Yisou's information about selling houses was repeatedly released the next day for several reasons:

1. Repeated publishing by the publisher: after the information is published on the first day, the publisher deletes the information for some reason and then republishes it.

2. Automatic system refresh: Some websites or platforms will refresh or update information regularly to keep the timeliness and attractiveness of information, which will lead to repeated publishing.

3. Others maliciously publish: Sometimes, others will use system vulnerabilities or publishers' accounts to repeatedly publish information, which is malicious.
