POSTING FOR THE FIRST TIME?
I'm guessing this is the best place to catch first-time BZ contributors.
As the forum gets bigger, spammers are trying harder, and it's sometimes hard to know whether a post is legit or not. I strongly recommend introducing yourself in the 'New Members' section. If not, at least put enough detail in your post so we know you're not trying to gain entry just to sell us big bright green pleasure machines or the like.
I had back pain too. But I did some stretches and felt better.
is exactly the kind of post spammers make. It's on-topic, but there are no specifics. Many first-timers jump in with posts like that. Sometimes, the name is a clue, but there are more and more posts from new people that are indistinguishable from spammy ones. Throw in some background so your comments are not disapproved.
