You don't actually need to use ninjastic for burst posting, but it becomes easier there. And in my thought, you are confused about the rule that icopress has wrote. If you wanted to avoid that, then don't make burst posts --> which means, don't make 30 or 50 posts in just 1 hour. Because that is almost impossible and the value it contains will also be lower.

So the best practise is to, add value in your posts because adding value will ultimately avoid you from burst posting. You should check this thread out for the Definition of Burstposting To be honest, I didn't consider a valuable post which is made just after another and another. But I consider a post burst posting when there is no value in it.

Many might not agree with me but coming back to your query. You just have to avoid making post after one another. But still, you should ask the manager because they might have different definition of burst posting.
