The a5 random talk area killed the external chain

In the a5 random talk area, you can only log in to view posts. Today, I found that only log in to view posts in the a5 random talk area. Spiders are not so intelligent and cannot log in at all, which means that a5 will have gray hair even if they send out external links. Is it a mistake by the a5 moderator, or is a5 going to kill the external links in the random talk area? My brother speculated that a5 would kill the external chain in the random conversation area. Nowadays, there are not many awesome webmaster forums. A5 is one of them. If you enter, it will be a water area. You know, the webmaster forum that feels less water is now the Baidu webmaster community. Push 18, 28, a5, webmaster forums and other forums enter a water area. It seems that a5 is starting to become stricter. It is getting more and more difficult to send external chains now...
