"They are making so much profits it's draining on the steem pool which effects all of us ! "

Well theoretically you earn rewards commensurate to how much value you're bringing to the community, it's not zero-sum where the community is worse off whenever somebody earns a lot of rewards.

You can make the case that steemsports doesn't provide enough value to justify the rewards they get and encourage people to stop voting for them. But accusing them of moral wrongdoing as @klye has done is silly.
