When in a server 2......

I got on a server today and there were 3 people online. The server was a ghost town. The three people left right as i got on. they were probally the admins. The whole town was destroyed. I saw sighns everywere. I looked at them and they said: GO BACK. LEAVE NOW. SUFFER THE RATH OF TNT. There was lots of sky scrapers blown up and shops left only with chests and sighns. i stepped on a pressure pad. i sank down under bed rock. Then i saw a nether portal BLOCK. That means hacks. In the nether There was a base with a sighn that said: Survivor base. I went in. The base was of bedrock. I got in and there was: Diamond armor,swords,TNT.Porkchops,and golden apples.
I knew something was going on.In the descriptoin of the server it clearly said: FUTURE TOWN OF MINECRAFT NO GREIFING FACTOINS MCMMO. But i realized that the server was at a greifing war. I left the server and deleted the IP. I went back to the site i found it on and the server was retitled: WAR SERVER NETHER VS HUMAN GREIFERS!!!!!

MORAL: A SERVER CAN CHANGE FREINDLY TO WAR
