Almost all my DGB friends are already kicked out. According to them the rules are:

1. Don't speak positive about other coins with better development (there are only couple better but still) or you will get kick out
2. Praise the development team all times.
3. Don't mention the premine or you will get kick out
4. Don't mention moving the premine to a safe multisig address or you will get kick out
5. Don't ask for detailed info (how/when it has been spent) or you will get kick out. They will tell only what amount was spent with a vague reason. No transparency.
6. They got an inner circle slack channel with only the real trusted members. They don't know that there are still some DGB fans in it. You would be scared if you know what they say. The discuss people kicking out of meeting if they come, share home addresses of people who question Gulden, share real names of people who question Gulden.
7. No freedom of speech. Obey the rules of Rijk or get out. This is why they moved from bitcointalk to Slack. They like moderation. They will use only moderated mediums because they want to be able to delete things.

I don't know which are true and which not but i certainly will not join their Slack.
