I have never paid heed to any of these useless offers. Resteeming doesn't become profitable even if they claim to have 30k followers. I have more than 3.5k (most of them active users) and but I have not seen my resteems make any significant impact on the payout of the hardworking individuals that I wish to reward.
I would say that treating them as scams would be best for the people because that's what they are.
