I used to do the same thing. But then I found this beautiful thing called "steemcleaners". Just report him using this https://steemcleaners.org/abuse-report/
They even pay you some SP in return, check my wallet if you don't believe me! You keep your voting power, get the spammer flagged to death and win steem power. Can't get any better can it?
woahh i just actually noticed how someone was getting paid in SPO from steemcleaners.... dude fuck yah good job! glad he was able to make u MONEY now! hahahah now i actually love @steemcleaners because of how genius that system is... a commenter on my post literally just got PAID to help report spam that i thought was gonna cost me to flag! NICE bro steemit never ceases to amaze me!
