I have posted a few links (One was to Tokyo University and the other was to Tokyo Tour boat service I was talking about.) I did read the forum rules, however I mistakenly interpreted them as "no advertisement" links. I did not think (at first) that all links would be banned. I do see that this would make it easier for you to monitor and control the content shared without following every link
Might I suggest that in the code for submitting posts you add a one-liner that says "Please do not post any links or other website names" in red. This would be an easy fix in the code and could save you lots of hassle!
