Questions about the DigLog revamp

1. Submission Filtering of Information. I didn't quite understand how the submission filtering mechanism of Diglog works. Is it through keywords or through titles? Anyway, I tried a few times and it kept showing that the articles were duplicates, and then directly redirected me to those articles.

2. Advertisement Display. Diglog allows for the setup of personal small ads, which is a great feature, but on the page display, they need to be specifically marked. Since many people use GG ads, which are already quite obvious, this essentially has no effect.
