They don't respond to queries or requests. I presume that's how. To avoid repeating my comments too many times, let me suggest looking at my other comments on this post.

Couldn't disagree more. I've mailed them twice and had a personal response within a few hours.

That’s good to hear. But I haven’t had the luck to hear back from them. So my guess is still that it’s a tiny team with many other priorities than this platform, and so misses responding or acting many a times.
