i just realized google's algorithm is so similar to the real world relationships. in the real world, we listen to other people to determine who is more trustworthy. for example, we ask our friends if they know a good doctor, and the doctor who is mentioned the most, will probably end up getting our business. my question is, what would be the equivalent of spamming in the real world? you going around and lying about a doctor? sorry if this thread is stupid, i am just bored.
