Merlin, no offense. In my opinion, if you were about one and a half times less active in all these three topics, Volgograd would have won without a doubt.
But you keep showing up and dominating. You dominate with your authority, experience, skill, whatever. And in doing so, you "devalue" Volgograd's application, which you are lobbying for (I don't think anyone has any illusions about that).

No. The mere fact that Merlin wrote often, and that this leads to such consequences in the reader's mind, is proportional only to the reader's own stupidity ("the reader's mind gets tired of reading all this").
To talk about the "devaluation" of Volgograd's application, it would be good to analyze whether anyone has changed their initial opinion about Volgograd to something else because of Merlin. And whether anyone has changed their opinion from other applications to Volgograd.
Merlin didn't start the argument. He was just fulfilling the mission he had taken on - to answer everyone intelligently. And in general, to try to resolve everything intelligently. For example, I immediately add anyone who engages in stirring up arguments instead of discussing the substance of the matter to my ignore list, and several new people have appeared on my list during the discussion of the CIS, but Merlin is not among them.
