The consistent posting of back to back with one person is even illedged as spam. Also as it's seen as they're chatting in some cases to get post count up.
But spam isn't inevitable, as it can be prevented.
Don't argue with idiots because they will drag you down to their level and then beat you with experience.
You're not double posting, so don't worry. Double posting would be posting two post back to back when they could of just been in one post. Which you havn't done.
