Cadebreaking is kinda tricky, since what you consider to be helping, the cade owner may consider to be hurting. If you so happen to be in a caded spot with an admin and what they see is you shooting at their cade they might just jump the gun and tell you to stop cade-breaking. If you were warned and didn't stop, you were rightfully banned (regardless of intent, since the cade was theirs).

But that's all hypothetical. Like Money said, post a demo so we can see what you're talking about. Just for the record (I haven't reviewed any demos) I wouldn't call this admin abuse, since this seems like more of a misunderstanding of intent.
