Would be nice if you guys would post helpful posts instead of off topic related ones. Either way. Thoto, you are having the EVM (Evolution Mod X) addon installed on your server, (You know, where you can transform more with super saiyan 2, that kinda stuff). The "Hellfire / Daemon" part is a "Anti-Cheat" implanted in the Addon itself. The Daemon has Its bugs, so the person you talked to was kicked and banned out of the server possible because he either cheated, or because the bug. I do believe myself because the bug, a lot of people are getting kicked and banned for it, even though they aren't cheating at all.
I'm afraid how ever the Earth's Special Forces Forums (this forum) does not supports any addons, so if you would be so kindly to
click here for more information about EVM, which will also contain a link to the EVM forums. So you could ask there or either search for the problem because I am willing to bet more people have the same problem.
