There is significant propability by just beeing here that you were hurt in the past and you didn't heal properly. First step before acknowledging the pain is to go to a safe place, where there are no toxic people and where your basic needs are met. Hurt people are like magnet for toxic people, and hurt people are comforted by familiarity of toxicity.
I am just guessing here.
I would say that it is just like random sample from statistics. You won't really get accurate count, but you will get a ratio beetween likes and dislikes.
