I'm sorry to say that an apology is not going to fix anything. You continue to make the same mistakes with your maps, servers and spam people on chat about your new content. There are people here that have tried to help you, you don't listen, and it just pisses us off. After all these years, you still don't understand that the content that you make is poor. I honestly think you want to help the community, it's the best you can do, but everyone else is just irritated because deep down, it sucks. So, you either need to get better or just stop. Now, if you're serious about improving things, this is what you need to do.
1. Go back and read all the suggestions that people have made to you on this board. Do what they say because they're right.
2. Stop blaming people for things that you need to improve on. (Uncompressed server maps, materials, ect).
3. Start working with people that are better than you at hammer. Do everything in your power to learn as much as you can.
4. Streamline your work into one thread or steam group. You could even do events as a way to get people to try your new content. Stop spamming us on chat!
It's going to be a long road, but you can recover from this. We are here to help you; but the change starts with you.
