I ask this question for a very simple reason:
I love voting on questions on any SE site where I learn new things, or recognize bad user behavior on a particular site.
What I'm asking is this: why we can't vote on questions on SE sites where we are not registered members? Maybe it's an issue with potential bots creating one SE site account and vote-spamming all other sites at random? Maybe it's some other issue that I don't understand. What I do understand is that I don't like the idea of creating 30+ accounts just for voting. Is there an explanation to this problem and design decision by the Stack Exchange team?
This is to say that, for example, I like learning things from Physics.SE; I want to be able to upvote questions/answers that I find intriguing, useful, etc. I want to downvote clearly bad questions and answers that I know don't fit the format of the specific site.
That said, I am looking for a/the reason why the SE engine does not allow for voting on SE sites where the user is not a registered member. Continuing the example:
I am not registered on Physics.SE, but I often find Hot Network Questions that direct me to Physics.SE that are very interesting, and that I enjoy learning from. I want to vote on these questions, but I don't want to register (yet) another SE account on a website where I will not actively be contributing.
I firmly believe that the people who ask/answer these questions deserve the upvotes (or downvotes) for the quality of their question(s)/answer(s); however, I don't think that it makes a lot of sense for me to register an account solely for the sake of voting on questions.
So here's the gist of the issue, in numbered format:
- I want to (up/down) vote questions on SE sites where I am not a member.
- I don't want to register 30+ accounts on Stack Exchange solely for the purpose of voting, when I know that I will not actively contribute to these SE sites.
I have already registered several SE accounts using Google+ Oauth; on 42% (really, a coincidence) of these sites, I have 101 reputation (the minimum as a trusted user), and on which I will never actively contribute. In fact, I would say that of my 19 accounts, I only really try to contribute to 3. I simply find the information on the other sites interesting and/or useful, and want to give the people who dedicate the time/effort to asking/answering these questions the credit that they deserve, without complicating my own SE network profile to have 30+ accounts.
As an aside, I realize that 'maintaining' 30+ accounts on SE isn't really difficult, with automatic login on sites where I am a member, cookie re-authentication that never seems to expire, and the simple fact that creating a new account takes only a few clicks and it's done.
The issue is more of a technical one - if I am interested in things that happens on all 100+ SE sites, should I have the need to create 100+ accounts just to vote on stuff that I find interesting?
PS - looking at this question from a 'meta' standpoint, I'm disappointed in my lack of SE data query data. I don't think it's possible to get the number of accounts for a user with analysis on the number of their total accounts that have low reputation (compared to their max/total for a site/sites). If anyone can come up with such a query, please feel free to add it to this question or answer. I think that it would help my case in that there are other users who create accounts solely for the purpose of voting on certain SE sites, and nothing more.
