You were making 45 posts in 2 days (4-5 March), almost each post only consist of one line comment. I guess it's clear why you got banned.
Another user,
Madness, which made 58 posts on 4th March also got banned today. Even though I think Madness's post is constructive, but somehow mods decided to ban him for 14 days.
I do not think it is the question of the 58 post in one day, if you "surf" in his latest post you will see he (Madness) also made 80 posts in one day. The problem (I think) is the content of these posts.
Maybe it is better to wait a reply from an admin.
I will say that you are almost certainly correct. I have made more posts then that over longer periods of time and have never been banned.
Fizda had not caught my attention as much as madness did but if you make low quality posts then you will likely eventually get banned.
