Considering you have followed all the rules and you are on topic, what is your average number of posts?
I am not sure if there are any restrictions on the number of posts because I have never had issues where I am told that I have exceeded the maximum number of posts per day or week. I have done up to seven to each posts in a day when I am on holiday and have some extra time. But currently, I spend close to two to three hours on the forum and my post count a day is between 4-6.
Additional question: For you what is the acceptable time gap during/while posting in this forum?
I think the forum places more emphasis on quality and not necessarily the time gap. Although fewer time gaps are one of the main features of spammers and low-quality posters it cannot be used as a scale to judge or assess the quality of posts. My time gain depends on how knowledgeable I am about a topic. If I have a vast knowledge about some topics, my reply might take less time compared to the one that I have to make research for more understanding.
