It depends on the moderators of the "magazine" (community) you are posting in. For example if you post your topic in my Pomeranians community, I might remove your post and give you the reasons for removal, but I probably won't ban you unless you go off topic repeatedly.
Another type of banning is called "instance ban". Instance bans are when a user is banned from an entire instance by the instance administrator. This means that the user can no longer access any of the communities or content on that instance. However, the user can still access other instances, unless they are also banned from those instances. Instance bans can be temporary or permanent, depending on the severity of the violation and the discretion of the administrator.
kbin.social instance administrators seem to be reasonable people. So I doubt that you would get banned if you follow the rules.
