You could always make your own thread like Ping's How to host a successful bet server and Devil's old thread back in 2012. But in your thread you could add the rules you think should be implemented in future bet servers. I personally think this is a great first step into getting these idea's implemented so that you could get other bet hosts to continue with these new rules.

I would love to see all if not most of these officially implemented, most hosts can almost make their own rules up now and it all honestly seems misunderstanding for those who go into different bet servers with different things going on, for example some hosts already do "/pause on" on the last frame and I have personally even set betframes to 20 in some cases so that people can bet first frame also to make sure people actually counter properly.
