I know this may look bad, but if someone could help me with it, it would be well appreciated. Is there any way I can make my own hack to hack back into my old server that I used to(but no longer) own? Some guy joined the server when I owned it, told me to change the name, and if I didn't he said he would do ''this''. And when he said that he made everyone in the server time out and just banned me. How do they do things like this? Please help me.
