I do not like to mention names, but this kid is really bad, his name is Seanconstant.
So, I just started in the server, I made lots of friends, and I helped my faction mine for about 2 hours, than this kid came on called Seanconstant. I had a diamond sword that time, and Seanconstant had Nodus, as you can see in the picture. I killed him, and thats when it all happened. He kept flying, and I killed him twice when he was flying.(Epic Fail lol) After that, he kept spamming, combatloverz dosen't know how to PVP, and he called me a hacker, when we was hacking xD, so this is just a story, but whenever you guys see Seanconstant, be warned.

Spammers
Spammers usually are on servers about at midnight, because the admins and all OPs are off. They usually get raged, because they either get killed, or they are bored. Most Spammers use Nodus, because it is like the only popular free hacked client.

How to take down those ****in Spammers
The best way to take them down is to have NoCheat, or NoSpam or anything alike. Another way is to basically kick/mute/ban them. Most of the time though admins are off, so thats when Hackers come on. A good way to get the off is to make everyone disconnect for about 10 minutes, so he is spamming vs. the console, so he will get bored and leave.

I am sure you spammers out there are also reading this, remember in order to become successful in life, you have to take in your mistakes, and learn from them.
