Nice post! This came just after a day I had to relax my "rules" and wrote a post about them.
Yep, there's a lot of abuse going on in Steemit and unfortunately, we can't deal with that abuse, unless we relax our rules a little.
So, I find it OK to to upvote someone's post without actually reading it, if you know that that person is providing genuine value to the platform.
The alternative is letting the abusers take advantage of your Steem and Voting Power.
