Some of your edits on Stack Overflow have been overruled by a diamond moderator. It is very well possible that he gave you an edit ban. The edits added noise and applied markdown where it was not needed. IF the moderator manually banned you from editing, that is probably the reason.
An edit ban is temporary, but the duration varies. You might get a warning when you try to suggest an edit, telling you when you can suggest edits again.
Meanwhile, I suggest you learn more about markdown. You were already explained that block quotes are only for quotes. Yet in this question you used block quotes again for emphasis.
If you do not want to get edit banned again, then learn when to use markdown.
