The first time I tried to post, I encountered an error saying my post was spam-like. It turns out I wasn't allowed to include a hyperlink, even though it was just a hyperlink to another post in this forum. But the error message did nothing to explain what was wrong with my post so it was just up to me to figure it out. The second time I tried to post, I encountered the same error again. This time I had to do a lot more experimentation to figure out that there was one word the algorithm didn't like "f o c u s." Why? What's going on? Is there a way to avoid that error? Is there some way to know ahead of time what can't be posted?
