Filter to remove spammers in forums

[Karan Singh]

Is there a filter or reporting system to remove spammers in forums?

I'm noticing real estate agents and some others are spamming every post and it's really ruining the the quality of the discussion. 

Every question or discussion ends up being 30 agents spamming with "my market is best". Out of 20-30 replies in a post, 15-20 will be spam. They are so blatant that they copy paste almost the same message. 

I've tried reporting these with the current way and it's not having any impact.
