He knows exactly why. He posts a "word definition" a few times a day and used to bid bot them up to $15.

Basically building a dictionary on steem one word at a time. Then 90% of the post is a copy/paste template he uses in every other post. To finish his "dictionary" one word at a time would have would need to extract $1M-$5 in rewards from the reward pool. (Webster Dictionary has 470,000 entries).

Now he spams everyone who responds to me with one of 4 accounts:

@fuckthemarkymark
@fuk.themarkymark
@markymarksuxdick
@stopthemarkymark

All four are blocked from the front end as well as all future ones he creates.
You can see what I mean looking from partiko.

As a result, I put him on a permanent flag and just muted him.
