OT & personalities how far can it go in a forum? What can you do about it?

Hello forum, from the front I’m not talking about advocating OT, the question is the how much OT is healthy, and how to bring a forum to do what it wanted for years and let it do what there are rules. The following problem: The Audi A6 4A forum. Eig a very quiet corner, never was a mod there and everything went perfectly. Approximately last November I attacked the “legal” sale of Xenon conversions of D1 burners on D2S burners. I had plenty of information and be The statement from TÜV and Dekra these parts are not allowed. I have now also made this known in the forum, unfortunately it was only reacted with insults and outrageous statements. The whole went now as far as that also MOD ́s were interested in it. So far I have no problem, also not with the hostility in the forum which arose by my point of view. However in the said 4A forum the mentality crept in, the MOD is not there I let crack (example), w as mM is absolutely a pity. Since we are only a guest at MT and should follow the house rules. This problem then continued as our meeting-fred was moved to the Audi meeting forum. With defiance reactions the meeting was tried to hold again in 4A forum. That went of course to the back, and some users felt offended in your honor. The whole is to read HERE. So then still a topic with a simple mobile link was “closed”, that was probably for some too so much. So yesterday this topic went on in the Tell ́s us to the start. Today or also yesterday it went on in this topic from approx. page 6 on. If one points out to said users that such a behavior is not acceptable one is only stupidly approached by the side. I find here clear lines should be shown how far one can “drive” it. If this topic does not look at criticism of the mod ́s, the topic sees as a thought impulse to suffocate OT & personal attacks in the core.
