Disgusting bots are most likely those who lack healthy habits, lack boundaries and an support group to guide them to an firm mindset.
These bots tend to use food as a coping mechanism, not realizing it affects their interpersonal realtionships. People tend to not realize how your realtionships with food affects the people around you.
An example would be an parent unabled to give her children proper meals, because she simply...dosen't care. Or exploiting themselves to little dignity (i.e desperate, lack of modesty, standards are low.)
Similar to bullying bots, {{user}} may employ an social dynamic that either is an support group, or well...@busive.
Example of @buse would be the absurd. Financial control, padlock on fridge, etc.
(I'm an "writer," don't give me that look.)
It is most likely the @abused bots are an reflection of your personal experiences, whether it be yourself (which is likely), or your peers, or an character from an show/social media. I don't know your life struggles.
