No, I don't personally know anyone on steemit that has problems with you up voting your own blog posts.
We actually didn't care about comments either when it was just a few cents for visibility.
Lately though we're seeing people up voting all of their own comments for large amounts. This is not a good thing.
The pro-communist guy I was debating with started with like around a $3 up vote of his comment and we did enough back and forths to where he was down to around $1.50 or so for a comment... but I bet he up voted easily $20 - $30 for himself in his short comments in that back and forth exchange.
Now apparently there are people with a lot more power than him doing the same thing.
The pool of rewards is shared among ALL of us. So if they use this tactic they essentially are syphoning rewards to themselves and impacting EVERYONE on the platform.
I don't up vote my own comments. I do up vote a lot of comments though. :) I just do a small amount for each. I like to encourage discussion. Up voting my own comments does not encourage discussion. :)
Then in that context I have to agree, I do not believe I have ever up-voted my own comments, I will go through confirm that statement. But yeah the commenters I believe should not have the option available to up-vote their own comment.
Or at the very least we could experiment with disabling that and see what happens. It is not the only option, but it is one.
I agree.
