Wow, someone needs to be a Robot to post 50 Posts in an hour Human does not have such capability.

I think burst posting should be seen as a pattern for a certain user and it varies from person to person. For example, if a person just comes online and posts 3 or 4 posts in half an hour and then he only makes the minimum posts required for the signature campaign and also if this quick posting happens usually near the deadline of the signature campaign, then we can say that he is doing burst posting but if someone comes up with the below definition then he does not fall into this class, rather I would call him the forum lover who gives all his time to this forum
