As QS says, to hit maximum you would need 2667 posts. For a standard full time job of 40 hours a week, this means a post every 54 seconds for 40 hours.
These numbers are utterly ridiculous. To suggest a user is able to open a thread, read the OP, read the replies, formulate and type a worthwhile and non-spammy reply, and move on to the next thread, all in 2 minutes, let alone in less than 1 minute, is preposterous.

[EXPERIMENT] Testing the Limits of ShitpostingYou could probably crank it up to 80-100 posts per hour if you started jumping into megathreads and going
really generic. That's $30/h for essentially non-stop work. It's equivalent to about a 5.5 hour (per day) work week.
Make a script to generate generic remarks about "the bitcoin" and you'll find your margins increasing more.
