Beginner rankings will be subject to some restrictions, including time interval:

• Time interval between posts
• The number of PMs you can send in a day
• Time interval between reports to the moderator.
• Etc

Sometimes I have to ignore my notification bot to fast responding to posts of other users mentioning me or quoting my posts for reasons of burst post. Although I can still respond to each of those responses at the speed possible for a few minutes from the mention, but I end up not doing it very often. The problem isn't with the forum rules, but maybe the campaign manager doesn't want to see the burst post. I know, when the post quality is well maintained then the time interval between posts is not a big problem for the manager.
