If it is forbidden to write two posts with an interval of three minutes, then it probably need to write about this in the rules? I did not know about this restriction. Thank you for telling me about this secret rule.
Aren't you wondering why there are a lot of users in here whom the activities and post counts are too far from one another? Because this forum isn't like any other social media you are addicted to, like twitter. This is a forum. A simple "forum" word simply means a place of exchanging ideas and thoughts, not EVERY THING you can think of. I just wonder why are you so mad that there are no written nor published rules about the burst posting that could lead to ban, as if you posted certain topics that has sense at all nor contributes some answers or even questions. Also, not all "low quality" posts are deleted, as not all posts had attention. In which cases, depends on how often you post in a certain period of time. Which makes it all clear that burst posting + low quality of posts = cannot be deleted early.
Stop your tantrums. You already violated another rule, which is ban evasion.
