While I largely support, my main points of concern (as I see them) are:

1. Infrastructure capabilities: once it would be announced (if and when), the site would receive a massive amount of traffic, as well as DDoS (and other, more nefarious) attacks. The DNC can't even set up a proper live stream most of the time. If something similar were to happen here, the fiasco would be heard throughout the media and the pundits to no end.

2. Pre-screening capabilities: I assume a lot of questions would be from genuine members, but a lot of new users would also ask questions, and maybe try to sabotage the AMA.

3. Overall perception: at these unique times of riots and "plague," doing an AMA might be bad optics (or spun into being bad optics).
