I'm fairly sure questions towards Betcoin rep on public forum, where they want visibility, is fair to assk and answer questions in public. That makes roslinpl's work also here much easier.
Asking/answering questions via PM would be viable only if you want to hide questions asked.
This is a signature campaign thread, not the right place to have a discussion about Betcoin. Do that in their official thread or somewhere else, not here. That kind of stuff does not belong in this thread.
Personal attacks on the people who run the site and this campaign are not going to help you.
