You have bee deleting things that you shouldn't be deleting and having been causing a bit more in terms of difficulty versus contributions on the site. You have done contributions as well, but it's being overshadowed by some of your other work.
I'm going to block you for one month, after that you will be given a second chance. Gsbr has told you to stop with some fo your actions which you have ignored. Always leave the original credits on, as well as speculations.
After the month if you do any of this again, you will be blocked permentaely. Hopefully you understand.
