If it's neither pushing an agenda nor trying to manipulate nor influence, why is it that submissions to libertarianism.org are being made mostly from two accounts that do not seem to otherwise engage in this community? No comments, no other posts, just posts to libertarianism.org. Whilst there's nothing specifically in the guidelines against the practice of accounts that just post to one website, the articles do tend to be inherently political and are at least pushing the guidelines in that respect. Even if we assume the accuracy of the information is unquestionable, a very high bar that even the most respected of sources do not meet, the behaviour seems shady and makes me deeply suspicious that they will be pulling at least some of the other tactics that can be employed to mislead. Does it not occur as strange to you that the majority of content on that site that gets posted here as stories is being posted by people who have no engagement with this community other than to post links to that website?
