Raiding is the best way to get lots of things. When you are raiding make sure of these things: You have at least 16 TNT on you, You have blocks to place with, Water bucket, and to build a big TNT cannon with you might want to bring a little redstone.
First go to spawn or if your server has a wild, you can go there. Wild is just were there are some mob farms and outside of it is unprotected territory. To get there do /warp wild or /wild
go out of protected territory and go at least 2,000 blocks (the closer to spawn/wild you worse the bases will be). Then start exploring around and doing /f map every so often to look for claimed territory. Look up to maybe find a sky base or go on the edge of claimed territory and dig down to bedrock and place a few TNT and light them. Then try to use a TNT cannon to get into the base. However if you have a faction that has a has more power than theirs you can claim land from them and get into their base. For a sky base just go to the edge of their territory and pillar up to their base and blow a hole in it with a TNT cannon.
If you get lucky you might find a base on ground level that has good loot.
