1. ChartBuddy is a bot.
~snip~
A very effective bot if we're going to be honest - every day you have almost guaranteed 24 posts, which amounts to about 720 posts per month

Joking aside, I think the OP should focus more on quality than quantity - not that I think some of the mentioned members don't write quality posts.

If your company has products in gambling, you will find posters who are actively in gambling.
There are also quality posters there, but any company that focuses only on the Gambling board can achieve some kind of results only if they start competing with campaigns that encourage their participants to spam. A good post in that board gets buried very quickly with a ton of junk - therefore, for me, it is much more efficient that instead of focusing on one board, more focus should be on those users who write in several different boards.
