I meant finish the site, not clear everything from grid. My choice of word was bad.
The problem is you would have to bump the majority of the fleet to really prevent hem from generating income. If you are willing to waste your own and at least a few other people’s time, you could do it. You will need a few bumping battleship, a logi wing and I would suggest some to include some cap transfer over what your logi need to work as if your fleet get targeted by neuting enemies on field, they will shutdown every active mods you have running quite fast.
The reason this is not being done is because it’s relatively harder and it pays less in every imaginable way than pretty much every other activity in EVE. There ae better way to antagonize others in the game than trying to bump a Machariel enough to mess up his tracking while his 39 buddy still complete the site laughing at he bumpers for barely having an impact on their income.
People who want to play the “ass-hole” in this game already do so in a practical way. Messing with incursion sounds cool until you figure out what it actually require to have and impact and then they just turn to other activity because the effort is too high for the reward.
