Your server is not getting any users because your server is bad. You should work more and do more research about what people actually want to play. It's kind of like supply and demand principle. You copy everything from other servers and expect players. Things you need to do.
- Actually know the game
- If you are making farm server then make the drops actually make sense
- Be creative
- Respect the community and other server owners
- Either know how to code or get someone to work with you who does(Prof and Avci)
- Be fair
- Speak English fluently or do not post your shit server to a English community forum
And also stop DDOSing other servers because you are jealous. This will not get you any gain. If you think this is an idea you suck as a person anyways and no one will play in your server.
