"I'm a fellow citizen living in Switzerland ... I think urgent action is needed even in remote Korea."

This is a comment on an article published in Naver regarding measures to ban foreigners from entering the country due to the spread of coronavirus infection-19 (corona19) on the 27th of last month.

However, if you look at other comments of this user, something is suspicious.

If you look at the comments of this man who runs dozens of times a day, you can see the status of 'Youth in the 11th Army', 'Woman in their 20s', 'Accountant living in Sydney, Australia', 'People who worked in the memory chip business in China', 'Students attending Yonsei University' This changes from time to time.

This is the side that was revealed when Naver released the comment history from the 19th of last month.

Unlike before, where you could hide your comments from others, all the comments you have made so far have been revealed, and you have a basis for judging reliability.

The side effect of disclosing comment history is also noticeable.

Above all, the bad comments (malware comments) plummeted.

According to Naver Data Lab's comment statistics today (5th), there were 1,236 comments that were deleted due to non-compliance during the full period from the 19th to the 2nd of this month, when the comment history was released. It is a third level of 4,166.

Non-compliance is a comment that often comes to mind when it comes to bad vice, such as straightforward swearing and blasphemy.
The percentage of bad comments in all comments was also reduced by more than half from 0.46% to 0.20%.

The number of comments deleted by users was 728,000881 (9.33%), which was 40% less than the previous two weeks (119,357,12%).

An official from Naver said, "It seems that the attempt to run malicious comments has decreased since the comment history was released."

After the comment history was released, the total number of comments executed during the full period was 781,630, which was 22% less than the previous two weeks (995,155).

By date, the total number of comments showed a slight decrease immediately after the release of the history, but over time, there was a pattern of convergence to the previous level.

However, it is not easy to judge the existence of 'Comment Alba', which is constantly fluttering, even by revealing the history.

Naver can filter out mechanically running comments and so-called 'macro' with artificial intelligence (AI) technology, but if it is not such a pattern, there is no way or reason to sanction.

An official from Naver said, "It is difficult to judge whether the comment users are 'Alba' that they are paid for or whether they are voluntary."
