t will become spammed with posts asking for votes or promising rewards for posts and people will quickly get bored and the whole thing will collapse.
SO to paraphrase If people are allowed to post things i don't like, the whole system will collapse. Maybe the system where people can post what they want without your particular sensibilities as a filter is the system more likely to endure.
If this was a NC post, just offering money for votes, then i would see your concern. That's spam.
