The questions here should be, is there a maximum amount of post limits per day the forum has stated that should be followed by the community, No there isn't. The only time I know the forum restricts you from posting simultaneously is when you're a newbie. Other's are free to post as much as they want, provided they aren't delivery low quality posts, it doesn't matter how many post you post per day. Campaign either aren't supposed to detect how many posts we can make. If you're in a campaigns that counts only 5 posts a day doesn't mean you should be making only 5 posts per day. You can make as many posts as you want and the campaign manager chooses which best 5 he should qualify for the daily posts count same as the weekly quota.

Burst posting should be about quality as others have highlighted and I support that argument instead of quantity of posts. Personally my posts number can vary between 5 to 15 posts per day depending on how chatty I'm for the day. Some days they come in interval of minutes while others days hours and I believe same can be said about others too and weren't trying to burst post. When we can say a usual is honestly burst posting is when he makes a certain amount of posts in the last hours before the end of his campaign week, just to beat the cut for eligiblity of payments for that week.
