I was talking about Actfit to a friend yesterday and I'm glad you raise this same issue
It's a pity that Actfit posts are now consistuting nuisance on Sportstalk.. I really don't know why too much of these posts now looks like spam
7 out of every 10 content you see are Actfit
I am not calling it spam but I just skip past them because i don't consider them proper posts unless they have some content with them .
