I don't like questioning the admin's judgment or interest, but a single visit in Jambler would make him draw his recently drawn opinion. He either didn't visit it in December / January, or he did, but thought it didn't quite meet the criteria.
My impression is that
he knows that Jambler is not a mixer per se, but, if some can
interpret the things and consider it a mixer (
of course, some members of the forum do this only because it benefits them, but wouldn't some from outside the forum think the same for the same reasons?), those* who have convinced theymos ban mixers in the first place may think the same. And theymos already "plays on the safe side" related to mixers...
However, it doesn't matter much since, as very well said...
You can't beat the admin.
* This may not accurate, it may be that he just thought in advance to avoid "those" start questioning on the forum, for example. But it doesn't matter that much whether this is accurate or not, the logic stays the same.
