I have a ghost link every time a new user accesses the forum they see this link on their dashboard. After clicking on it, the link disappears. Is it recommended to delete the link or close the topic so new users will not see this whenever they log in?
I’m not sure I’m following. The link you shared appears to be a PM, the discobot welcome message. You can change the settings related to this automated welcome message by searching for discourse narrative bot welcome in site settings.
