I do feel as if you are over-exaggerating a few things here, blue.
Empty Buildings
Empty buildings are completely fine to me, I see absolutely no harm with them at all, unless someone has built on already claimed land. Some players have such large scale projects that they have no intention of even filling in the houses/buildings. It is not a rule that you must furnish a house with a bed, flower pots, or whatever you may want a house to be filled with. As Hominix stated, this world has been going for a long time. (Since October 2013, near 1.7's release I think) The world has been going a long time, and with the server being pure vanilla, commands like /wilderness would break the vanilla aspect of the server. I would say exploring in Minecraft is one of the best things to do, I love trying to find Mesa biomes, or a nice spot to build in a Mega Taiga. You may not agree that exploring is fun, but everyone is allowed to have opinions!
The Nether
The Nether Hub, as stated by Hominix, is simply for convenience's sake. If you really badly need netherrack, it is really not difficult to find it. Having been to your base before (I believe it was with you), I know your tunnel is (or was) made of pure netherrack. Complaining that you can't find netherrack is wrong, considering you had to only go through a portal to find it. Netherrack is almost the most abundant material in Minecraft. You only had to ask for some netherrack if you needed it.
Spawn
As for spawn, your personal opinion is your own. Although I do think you didn't need to go as far as to say spawn looks like "dog vomit". This is similar to an issue a lot of other things have, such as YouTube. (I won't rant on about YouTube, don't worry) The dislike button is merely pointless, unless you explain in the comments why you don't like what you had seen. This can relate to this, you give no reasoning as to why, or what changes you would recommend making. Either way, I have no idea what plans Zed or Lady have for spawn, but the most I know is they are putting build-off competition winners in the blank areas.
The Community
This community is by far the best public vanilla I have found yet, hence I have almost been on Zedwork for 2 years. If I didn't like Zedwork or the community, I would have left few days after I joined. This community is friendly in general, although you will always get new players coming on with bad intentions.They are swiftly banned. We are only human, we all make mistakes.
I'm glad you went on to state you like the server, but I do think this "rant" was a little too over-the-top. Everyone is allowed their own opinions on matters, although it is better to back statements up so the other person can get a better understanding of where you are coming from.
