Being in unfamiliar territory, I am using terminology which I understand. I was almost certain that 'shitposting' would not effectively convey the concept to anyone but myself, but that's better than using language which leaves the thought clear to no-one at all.
My idea can basically be phrased up as such: where town has no information at all and at least one other opposed party does have information, it is of benefit to lower the quality of all information in the game e.g. by deliberately being disruptive about a non-issue, or by giving deliberately deceptive information.
An extremely pure example of such is fakeclaiming a role which does not exist in the game, such as claiming rolecop in 'vanilla' mafia ('vanilla' being cop/doc/3xvanilla town/2x vanilla mafscum with N1 before D1 in this case); this may have very little effect on scum's grasp of the game, but it has a far greater (if negligible) effect on such than on town's grasp of their own role. In particular, the wifom surrounding such a claim with regards to it's impact on one's likelyhood of being the actual cop is the most likely aspect to distract scum, whereas the player may have resolved to make such a play before the game began. Of course, the objective here is to cause scum to make a mistake regarding the information they have by flooding them with confusing and irrelevant information, as it is far easier for town players to identify what information is not available to the town than it is for scum to do so. In a straightforward game, scum have no trouble with such because the information available to the town is straightforward and minimal. In a phenomenally muddied and unclear game, players in general, in particular those with more information than others (i.e. scum, but also power roles), are likely to make mistakes regarding information. Forgetting information available to town raises suspicions of being anti-town because it suggests sloppy and distracted play, but revealing information unavailable to town raises suspicions of being an informed minority.
To give a less theoretical example, consider blackmagechill's D1 lynching in Mein Kampf. He was very busy, concerned, and flustered on D1, and he did not notice that he was speaking about information unavailable to the town in high modality language. The fact that he did not doctor his flavor or realize the need to do so (when the need to do so had been discussed in the thread (regarding flavor given to the scumteam in WC)) shows that he did not have the opportunity to give as much thought to the information that he did have as was ideal, in no small part due to how much of the meaningless information created during the RVS discussions he engaged with. Yet, he had no choice but to play the way he did; to fail to engage with that meaningless information would be anti-town for refusing to give reads. Deliberate anti-town behavior, if out of character, is undeniably scummy.
The goal of a town with no information is to create discussion. The quality of that discussion does not matter, merely that the discussion resembles legitimate information which may arise within the game.
