Oh my Gosh,
First of all, removing "download" section will not help. Everyone has rights to publish their own work on the internet if they only want to. If not, they keep it for themselves - I think that is fair enough and simple.
Secondly, as I said, everyone can do whatever they can after downloading a datapack. You will never stop noobs from creating their own noob open tibia servers. The only thing you can do is not to play on them. But seriously, if someone likes a server, even if it's the noobiest server in the world, why should we tell them to stop playing on it?
Thirdly, even a noob will realize that something is wrong with his server after he bought a dedicated server and there are only 5 people playing on it. He will mature and he will say to himself "well, the next time before I buy a dedicated server, I will add some systems to my ots" and another time he will add a website etc.. That's how everyone started.
Sure, there are some noobs that launch some noob servers on their PC and they ask for donations and the next day, the server is being closed. Well think about it... Is the hoster the only person that is stupid? I think some players are stupid as well...
Just a quick word about having fun while making server. It's not neccessary to have fun while doing server. Some people are doing it because they feel they are good at it and it's a good place to start and then go to another game.
I must say one thing. Open Tibia Server is actually a great skill training for programmers. It includes like pretty all areas of programming that a programmer needs to know and by that I mean different programming languages like: lua, xml, c++ (very important), html, css, php, javascript (very useful) and lots of others. So why should one not try to improve his skills by making a good open tibia server? He might not have fun with it but he is good at it and he gets to learn new stuff.
That's all for now ;D
