As a side note, someone could potentially create many useful posts in a short period of time (although maybe not 100 posts in an hour), if you have sufficient knowledge of bitcoin related subjects.
The metric is really to form a kind of idea on how many posts I can make under the context of "barely-passable" or "sufficient" post quality. If you take a look at a large portion of signatured posts, you'll understand what I'm talking about.
You needn't reserve a post for this.. You seem to do this a couple times: make an OP and make a post reply right after (so essentially a double post). I don't care - but note some people might thing you're doing only it for the signature payout too.
I don't think I've done it too often recently: maybe twice outside of this thread. Doesn't really matter to me what others may perceive as "posting for money". Those that know me should know (to some degree) that I don't just mindlessly post to hit the cap every week. I also trust in DS's ability to not tick a single line "Reserved" post as qualified.
This is not going to do very much. A manager does not need to be "not banned" to do their job as a manager, and they could potentially do their job in its entirety off the forum without even disclosing their account.
Which is exactly what's happening here: something that I've feared. High-count low-effort campaigns that induce spam, hosted off-forum.
