I ll quote some comments from wowhead retail to prove that silithus nodes are not an abusing and try to change the admins mind.
1st comment: Qinella on 2008/12/06 (Patch 3.0.3)
I ran the circuit in Silithus and can confirm it is a great place to farm thorium. Just run through the three major hive areas in the zone. There are about 3-5 hives per area, varying in size. If you are high enough level, just run right through and don't fight anything unless you have to in order to mine. The mobs there have a short leash and will snap back after a few seconds if you just run away. I'd say on average I got about 3-4 stacks per circuit if no one else was in zone. You can also find regular thorium veins if you run along the zone border as you go to each major hive area.

I actually make a good amount of money farming these on my rogue... make the stone and thorium, and sell thorium shells, then if I get an arcane crystal I get it made into a bar and make it into a converter, then sell that as well.

I think this is the best place to farm for thorium on a rogue. There are lots of rich nodes, very little competition, and plenty of small ones scattered around as well.
If you run into any of these nodes in a room with Hive Zora Wasps in it, leave it alone unless you have a death wish. They are all linked, so if you aggro one, you aggro all five of them (they always seem to be in groups of 5+) and their poison quickly stacks up 10 times. Hive Zora is the nest on the West side of the zone.

Doublewire's comment is fail. I am actively farming these in Silithus in each of the 3 hives and the most I have found is 2 per. "5 veins to a major hive" LOL That would mean that at any given time, there are 15 veins sitting in Silithus waiting to be mined, ALL AT ONCE!
btw I am the only person in Silithus atm. Including Allies.
Blizzard changed the nodes with small ones on patch 4.0.1 in the late 2011 there is the last comment that i will post to prove it.

It seems that Blizzard has taken these nodes out of the game and replaced them with small and rich thorium veins. I just took a trip to Silithus to farm them to level an alt's engineering and was surprised to see no ooze-covered veins at all. While I am not 100% sure of this as I did not take the time to travel to each hive, Hive Ashi in the north held only a few small veins. You are probably better off going to Un'Goro Crater to farm thorium. Feel free to check it out as I did not confirm this, but you may be disappointed by what you find out.
