I think it's ok for people to vote for content they like, for whatever reason. I don't go to pixabay, twitter, fakebook, imgur, etc., and if I see content here, where I do go, that I like but wouldn't have otherwise found - and it's properly attributed, so not plagiarized - I show my appreciation with my $.02 vote.
I also spend hours on comments, and posts, that I neither expect financial reward for, but share because I believe it's important. I just recognize that not everyone can do that, not everyone wants to do that, and sometimes not doing that is the right thing, so just look for folks doing what they, and I, think is the right thing to post.
Am I wrong?
Yeah, well put. You're right, people have the right to vote for content that they like. I don't necessarily have a problem with it if it's referenced well and of interest. And you're correct in that there is some brief content that I wouldn't find elsewhere if I didn't see it here. But sometimes it's evident that's not the case and that the motivation behind the post or series of posts is purely financial.
