I agree anyone can comment on a post, this is a public platform. But this service is an automated post, not by a person producing a comment directly related to the blog post.
If someone was really interested if a person is using a bot, they can look at the wallet. If they are that interested, it only takes one click.
And what is anyong going to do when they see a post used a bid bot? If it was for $50? Are you going to flag it? What is the outcome?
You are not going to flag every post that uses a bid bot. If you did, you would get so many downvote flags that your future posts would not make .01 for the rest of your time here.
I do agree that some people are abusing the service by gaining 100's of SBD/Steem on every post. They should be the one's who need to be notified of their actions and the impact on the 'trending/hot' page and with the rewards pool.
Bot votes are an automated system. No one read the post that got voted on, but the value of it still increases...
I've flagged many posts for abusing the upvote system, have gotten flags from people for nothing other than the person was butthurt I had the audacity to negate some of those rewards with my democratic vote in one direction or another. I shrug them off.
As I said, the tides are turning against bid bots and their users. The overwhelming use of them has led to such the need for an automated transparency effort.
Could the comment be restructured, sure. Is the whole thing worthless or spam? NO.
