Many kinds of bots are basically for abusing an open platform to gather tokens by doing nothing oneself. Greed is usually behind cognitive dissonance, where no rational explanation about possible harms does not matter. For example, a knife is good for cutting vegetables, but some people use them to stab other people.
So these programmed tools can be good in some situations, but it creates an incentive to stop communication with the community. Some are straight harmful, like this one person who spams warnings to comments for people he does not like, or thinks they are bad humans.
Basically you cannot stop the abuse, but most definitely they will ruin the system in the long run. In crypto world there are thousands of examples, where honest people leave and it becomes a cesspool of people tripping each others over.
