I use it and to be honest, I am only doing it to help increase my reputation. My schedule and typing style doesn't really allow me to make a well written post every day.

It's not all that effective. Most of the time no one replies. And all of the upvotes are coming from low rep bots, not real people that you can build relationships with. All you are really doing is cutting into your payout profit since the service is not free.

Honestly with a reputation like yours, I don't think it would be worth it to use them. I don't know if I can say the same for newbs like me.
