It's worth considering why HSX exists in the first place - to generate data about future box office from trades made on the site, and sell that information on to its customers. So HSX wants trades to be based on fundamentals (will the movie get made? what's the budget? who is directing? who are the stars? when's the release date? who's the distributor? would people want to see it?), and less on following price movement. This should make the data better, and better data generates more revenue for HSX.
HSX can't prevent traders following price movement. But at the same time, it's known by everyone that if a stock is mentioned on the boards, it generally gets an uptick in price (unless it's actual, bad news). So HSX comes down on board posts that could impact price without affecting the fundamentals - old news, astro-turfing, thoughts about how traders will trade a stock, etc. Posts by established, successful traders - such as fund managers - have more influence with traders, and theferore get extra attention.
If you find this too restrictive for your personal style and decide not to write a regular fund report, then that's fine, it's your call and please keep making us money with FOXX. But at the same time, you should understand why the etiquette about what can and can't be said on the boards exists, and work with it instead of against it.
(Full disclosure: thinking back to my own FOXX reports, I mostly spoke about upcoming openers and how I thought I should play them, but there were definitely some times when I crossed the line and talked about money-making opportunities from day-trading IPOs, etc. Mea culpa.)
