Hey, the same thing happened to a post I made that specifically promoted a community project I launched to build a collaborative library for Pianobook. The only external link was to the launch video, nothing offensive and no commercial promotion or anything. It was deleted without notice. I am clueless as to what was inappropriate about it as it was exactly about what I assumed to be the whole spirit of Pianobook. Maybe the forum rules that determine these deletions could be made transparent? Or is this indeed an algorithmic thing?
So the first post I made contained a link outside of the < l i >< /l i> code. That one didn’t post. But when I included the link in the < l i > < /l i > code, it posted. If you press the li button between ‘ol’ and ‘code’ it seems to work. It’s most likely an automatic thing?
