Yes that is true.. but since steem is a cryptocurrency which can be bought and be powered up to SP, there is nothing much we can do about that.

However what i am concerned about people skyrocketing their reputation score to 60 in just 10 days bu getting huge upvotes from bots..

Reputation score was designed as a measure of someone's level of engagement within steemit community and that should be earned and not bought..
thank you brother for the analysis :)
