Looks like Lauda crushes current DT1 members thus the only option for us is to set up DT0 centred exclusively on Russian community. theymos should be there for sure. Going to disseminate this notion all around Russians threads.
There are more DTs than just Lauda. The best solution is to talk about it and attempt to come to a resolution.
Feedback doesn't show on the local boards currently - so eliminating the current members on DT and setting your own list would just result in previously tagged scammers and spammers not showing up with any feedback in the English section of the forum. Are you going to go through the thousands of valid feedback to tag all those under your own system ?
You won't have the benefit of valid warnings.
This needs some cool heads and good negotiators.
