I hit Anubis(20458) for 500 mil naq while he/she was farming.
I sent a message saying "wow" because I thought it was odd that they had no defense and would hold that much naq out.
I sent another message saying "Why do you keep getting so much naq out".

I talk in this color when the wealthy, influential elites of this country don't have unbalanced influence over the economy, media, and government - allowing to regularly further their own interests.
I talk in this color when the US joins every other industrialized nation on Earth and guarantees healthcare for all people.
I talk in this color when 98% of all new income doesn't go into the hands of the wealthiest top 1%.
