Source: Any Downvote on Peakd :p
Like Seriously? There are numerous amount of people here trying to scam the system in some way. Unknowingly or knowingly, that makes it kinda our job to take our hands off our dicks and regulate it since we dont have a centralized entity to do so for us nor do we want a centralized entity to do this for us.
I have heard this a few times "The witness are centralized" or The witnesses are bullies", you may not like the current witnesses chosen, but they are still chosen by the vast majority of the community to uphold this blockchain and they can't do it single handedly, they have to agree on stuff before a decision is made, so I wouldn't call them a centralized entity. (P.s Friendly reminder to regularly check your witness votes)
I think the biggest problem is that we don't have any formal rules on how to act on the Hive blockchain, its so vast and people do a lot of different stuff and we also don't want to limit the innovation of dapps, but that doesn't mean we don't have some unwritten rules here even though its still kinda the wild (kanye) west here 😅
Lets get this clear first. Anyone is allowed to exercise their downvotes the way they want to, but many choose not to, maybe out of fear for retaliation from bigger accounts or because they don't care enough.
If someone is dick-fuck-raping the reward pool that means less rewards for you, thats why you should care. In theory at least and no, It can't remember the extract amount of HBD there is printed daily.
Lets get back to some of the unwritten rules which I know of
Plagiarism, Plagiarism is a no go here and you will get downvoted 100% if you are stealing stuff from other places on the internet also copy/paste and also if you just translate something from one language to another.
Spamming, Spamming is a bit weird, you can post a lot of post here daily and thats not really a problem, the problem arises if you post the same post multiply times and in multiply communities, thats not okay. We have a feature on 
Identity Theft, Identity Theft happenings now and then here and its kinda a mask spamming effort to get more rewards on more posts.
I do also think we need to tell people why we are downvoting them and explain to them what they have done wrong and how to fix it, because we just starts to downvote a shit-ton. It takes more effort I know, but I think its worth it to at least give them a chance to change.
