We should all know that volunteer Admins for a free server don't have the time to do everything that even they would want to do; so, I thought I'd try and help other new players not waste time with plans that might involve potentially banned items that haven't been added to the list by posting about what I've found to be banned so far:
Thaumcraft:
Golemancers Bell
Computer Craft:
Wired Modem
Wireless Modem
Rednet:
Rednet Controller
Rednet Cables ( this is different from Rednet Energy Cables)
Tinkers Construct:
All of the "Travellers" gear (gloves, belt, etc.)
Witchery:
Poppet Shelves
Blood Magic:
Teleposer (this item is on the list but it is not listed as from Blood Magic; I haven't checked the Teleposer from the ProjectRed Expansion yet)
I will make additional posts if / when I find more items that are banned. This list is not an attempt at arguing the reasons for an item being banned; that's a topic for another post(s).
It is worth mentioning that some of the items on the posted banned items list are not currently banned; I've seen some of them in use, and use some myself regularly. Unfortunately this means that sometimes it just takes trying to make or place something to see if it is actually banned or not: which means that we all just have to take that automated "Ha! You wish!" response in good spirits and keep trying things (even though it's infuriating to have the server laugh at you for trying something you didn't know was not allowed... )
Hope this helps someone. Good Luck and Have Fun!
