Any site that becomes sufficiently popular will attract sock puppets, shills, paid agitators, paid astroturfers, spammers, scammers, people paid to warm up accounts and to vouch for their alternate accounts, accounts pretending to ask questions with alternate accounts that suggest a solution that they own and operate and many many other shenanigans. There are also no shortages of people that try to influence the thinking of others or trick them into buying something or voting a particular way. Some of them get nullified in /newest by some of us. Some make it through. Some even get massive responses and that is is a chance they are rolling the dice on.
