I own a wp site and I am in the habit of just deleting those spam posts. Fortunately WP has added a spam filter to their service, so the problem has nose dived.

Maybe we will see spam filtering in steemit, but it may be a while.

I have seen really good fact bots, and good link bots, but yeah, what you described is in the category of crapbots. It is almost as bad as the IRS email and phone calls.

Just remember, just when you thought things are going to get better, a new butthole will prove you wrong. 😄
