I can only think that it will take a fortune to be actually able to fund such an operation, that board will need at least a few tens of mods , even small boards are hard to keep "clean" , the problem with that board is that people don't use the "report to moderator" quite often, simply because the majority are there to gain some worthless tokens here and there.

it is safe to say that with the current "freedom" this forum offers to it's members, there is nothing much that can be done , if you really care about that board (most members don't ) then simply start reporting spam/off-topic posts.
