Blizzard, it's time to start perma banning some people who use LFG as their personal advertisement platform

I'm sick of the fact that 30% of my LFG list are people selling +10 mythic boosts when having a raider score of 1100 themselves. (not that a 2k score would justify it) Want to get rid of those people? Have a GM perma ban every person with their twitch / boost tags in it for a day. Strike some fear into those people that you are activly cleaning them up. What is my report for advertisement even doing at this point? BESIDES HIDING IT FROM MYSELF? Is Blizzard actually doing something with it or am i just wasting my time? Pretty sure it's the latter
