Your profile has now been changed to autoban and should not only restrict you from sending messages but also you can't post anything on the forum. Plagiarism is actually very hated by forum and every user has been warned that if you break the rules, you have to be prepared for the consequences i.e. autoban.

To be honest, I don't know if the mod will reconsider your account and forgive your mistake after breaking the plagiarism rules but if you really do it on purpose it will be hard to get an apology. I don't know what contributions you've made so far for mods to consider, usually it's also useful (but not all).
