If you make a map as the sole point of truth, it can also be used by anyone to traverse in. Would be an interesting experiment to see how gamable it is to have rotating & contextual maps. The users don't care how objective the wot is anyway, so long as it effectively filters their experience.

The map does not react fast enough to abuse.
Is it not possible to separate the different components of a monolithic wot into multiple ones? Of course, some get outdated but if there are 20 different metrics, often in conflict or deliberately worsened - you'll have something quite difficult to game.
The problem is what differentiates a real user from a bot. No WoT algorithm can solve for the lack of that difference if it exists.
i'm not sure if this is really true. wot algos can factor in many things like zaps and how often you interact with them. yes its not perfect but it can be pretty good.
You definitely can't filter out all bots. Some users even explicitly care to interact/follow bots. You can, however, filter on credibility. But like irl social credibility, there are different interactions you can work with to establish it. It can be context dependent, but i think even some sort of random rotation between them would be effective. I don't have evidence, for these claims but I think it would be something interesting to play around with, especially in a space where so many are searching for "the best wot algorithm"
