I have buyed some redsand and i have transformed into sand and crafted TNT . I saw that it is useless to my so i tried to sell it and someone said that its illegal. But its not on /warp illegals. So im asking abouth it.

 

Yes, it is illegal because you use sand to craft it which promotes island farming.

 

Ok ill throw it out

 

Rule 8: Do not trade or give illegal-to-trade items
Offence Level: Medium
The server has lots of illegal items that can't be traded. The list is pretty big, so it can be over whelming. It is best to message a mod or donor if you are unsure if an item is illegal. This is the list and why. (This list is for .net, it is different per server)

1. Dirt (Starter item, you can vote for grass blocks (turns to dirt))
2. Sand based items [Sand, Sandstone, Smooth Sandstone, Chiseled Sandstone, Stairs Sandstone, TNT] (Starter item, donate to get a kit to get more on Survival, buy from /warp shop on Economy) [All glass products legal to trade on Survival][Stained Glass, Stained Glass Panes, and Glass Bottles are allowed on Economy]
3. Silverfish Spawn Eggs (Can be used to grief without creating logs) [Survival Only]
4. Steve and Wither Skull Heads (Never released & Withers) [Survival Only]
5. Buckets [All Types] (Starter item, get more by getting iron)
6. Sponge (Creative only) [Survival Only]
7. Bedrock (Creative only) [Survival Only]
8. Podzol (Not sold by traders, on starter islands sometimes due to glitches)

As Fatal said, yes TnT is illegal to trade. Plus, here's the rest of the "Illegal to trade" list incase you have any other questions about any other item.

Other than that, is your question answered?

 

Warp illegals is currently outdated and it is suggested to use the following link Server Rules | Skyblock Forums

 

Exactly, which is why there is a new project coming out shortly for this. Not saying anything more
