(I see it's totally demotivating from newbies point of view). We should better work on helping people to adapt to this crypto community rather than trying to harass or frighting them about the rules as soon as they post something.
May I ask what you're referring to here? What are newbies getting harassed for doing? Hopefully you realize that a lot of the newcomers to this forum are only here to make money from bounties and sig campaigns, and judging by the amount of ban appeals in Meta they don't seem to be reading the rules before they break them.
If we want to have a forum that isn't clogged by nonsense posts, members like the aforementioned ones
shouldn't be welcomed with open arms, because they're the ones responsible for how bad bitcointalk has gotten in terms of readability. And that small "group" on DT that people keep referring to tend to be members fighting against the useless spammers, account farmers, account sellers, and assorted scammers. They've also left a lot of accurate feedback in that fight, which IMO is a good use of DT "power".
Its embarassing.
It's embarrassing for you because you got knocked off DT. I don't think the majority of bitcointalk members share your opinion that the current DT1 list is some sort of terrible injustice. In any case, I never lobbied to be on DT2, much less DT1. Lauda wasn't even on DT anymore when he/she was added to the DT1 list. It was Theymos's algorithm which was responsible for all of these changes happening, not some conspiratorial power grab by a select group of members.
Again note the regular use of personal attacks and hostility from the types of people who fancy themselves as forum police. They only know how to speak the language of threats, accusations, mobbing and inquisition. A lot more people share that opinion than you think, they just don't care to get wrapped up in all the harassment that follows bringing this information to light. Anyone without a reputation is simply dismissed as a scammer and anyone with a reputation has something you can leverage over them to force compliance.
There is no reason you and others still can't continue doing what you are doing to help the forum just because you won't be able to leave negative ratings like handing out candy. None of the things you listed require this in order to be done. Furthermore it ends up being little more than noise actual larger frauds can hide behind in the chaos of all the conflict. You just will not be able to lord arbitrary negative ratings over people in order to force compliance with every pet issue you have. The constant refrain from the wanna be forum cops is the sky will fall. It is getting old. You won't restrain yourselves so some restraint should be imposed upon you.
