Best poster i have seen when i checked dadice spread a few weeks ago was Quickseller at 150posts a week, do you have a bigger poster in Bit-x? so 100 post limit is fine and good for the forum as it discourages spam.
OP i checked your recent posts and i have to ask marco did you kick/remove him because of spam?
I've had days where I made over 50 posts in 24 hours although they usually involved me not doing anything else and not sleeping. It's extremely difficult, and definitely not sustainable for most people in the long run, but for someone who is retired or otherwise not working/studying and is also very interested in Bitcoin and cryptocurrencies, I can see how they could easily make well over 100+ posts per week.
For example, hilariousandco was one of the top posters back in 2014. I mean, he still is, but he posted way more frequently back then. And pretty much all of his posts were constructive too. I wouldn't be surprised if he went over 300+ posts during some of those weeks.
and the rates not bad
