What is the solution to this kind of comment spam? #flagclub

A not so ethical guy named Hive account@andalucia was spamming my thread with "1" comments. Yes, he wrote 1 in all of his comments:

I emptied my VP by flagging his crap comments.

But it appears that he has done this in other threads as well. His comments tab is full of them:

Scroll down and more one comments:

#flagclub anyone, please flag this guys comment spam.

Public disclosure: Flagclub is a community of steemians who believe flagging shitposts, spam, comment spam, plagiarism and all other forms of steem abuse is bad for steemit's growth and they should be flagged to the bottom of the sea.
