Weibo's remarks are mainly due to regulations in various media, because many press and publication administrations have issued articles. In Weibo, if a reporter is V, his remarks are equivalent to those of his media, and then the media will monitor the reporter's Weibo in real time, making it inconvenient to send things.
Writing comments in your own media is another matter, because many comments or reports are negative. If you sign directly, it will offend people and others will find trouble, so it is safer to use another name than the price.
For example, sometimes, some newspapers have several pseudonyms as public pseudonyms for publishing negative reports.
