Hello sir,

Steem Curators must not have recently powered down (30-90 days.)
What is the easiest way to check that?

The easiest way is to check through steemword since most tools have stopped showing that. Maybe steem-seven is another option but I haven't checked that for sometime now. There was another one by Gorilla and if I remember right synthesizer or a similar name.

I have not selected three teams so leave them to Steemit Team as for giving reasons for not selecting, I can tell you a couple of reasons but avoid saying them for obvious reasons.

I have replaced @chant in one team. Thanks and regards!
