You should make use of the report to moderator button if you find a particular post you see as a spam or unnecessary post. Other members here have also suggested some possible things you could do. Nonetheless I think it's better if you had just made this post with your real account and not an alt account.

It's high time people here had the esteem of if you can't post something with your main account don't bother posting it at all. I think you've gotten good replies about it already and I suggest you lock the thread to avoid spams too.
