I saw a product, it had a 1 rating. I added a higher rating. The total rating went down... bug?

As always, the problem with this kind of site is that as soon as you gain any kind of traction the marketers and bots will come and ruin the rating reliability.

Not a bug but I understand why it looked like one. We just switched to Bayesian scoring to prevent low vote entities gaming the rankings. Your vote is counted, it just takes more votes for the displayed score to diverge from the baseline. UX is being improved. On the bots point: votes are trust-weighted (account age, consistency, cluster detection) specifically for that reason. Appreciate you reporting it.
