Looks like it's made $23.25 so far @ 1.50$ for the message.

If it reached 5$, he'd have made 25,000$

Your math is off -- if it reached $5, he'd have made $250. I think you were counting in cents. To convince yourself:

>>> total = 0

>>> for i in range(5, 500, 5):

... total += i

>>> total

24750

Hey you're right, my bad.

But there's all the hosting costs to consider.
