@hivewatchers spamming and farming hivee

LOL , @hivewatchers post 70 to 100 spam comments everyday and they are upvoted by 2 accounts every day, is anyone else allowed to do this? and they get almost $1 per comment. But i guess this is ok, why dont they decline payment on all their spam comments or are they here only for finacial gain. They have farmed almost 10000 hive this way.
