I don't know how to run a server so I alway's go looking for ones to play on. So this morning," By the way I have not bought the full game yet so I was playing free version", I clicked on the website and there were the three most full formums at the top. I cliked on the first one and it sayed it was a free build, meaning that anyone  and every one in it could build, so when i got in I was suprised to see it was a huge map but realy crowded, It sayed only 500 people were in it but it looked thousands,  even weirder, it only had a few people building in it so I tried to put down a blue block but the screen sayed" No building in this world", so only the so called highest ranked people could build, so right before I was about to leave I asked some one else why don't they just leave. They sayed they could not. So I left the first one and went to the two below. When I stepped into the second one i't looked like the one before, then I ran into the guy I talekeed to before and he sayed, "I thought you left". I did to so I went to the third one and it sayed freebuild too and what do you know, it was the exact same server. So then I sayed what the heck and checked out the less populated servers below but when i clicked into all of them they sayed server to full when they onl had like 25 out of 70 people in them. So I think that those three biggest servers made a deal with minecraft so they can be the only playable servers. But maybe im just parinoid. So tell me what you think and ill try to respond, By. (P.S.) Sorry if theres bad spelling, i wrote this in a rush)
