@ccoutreach87 The platform does not have any restrictions related to posting, however all individual users have full control over whether or not they block another user.
It’s usually good to post things other than links from time to time, it increases to human interaction and helps to guard against the impression that you are a bot.
@ccoutreach87 yep. exactly as @katharos says
personally I just skip over the posts that are just links
We're a friendly community, but get to know people and give us time
