I dealt with them in the past and they are very good. My guess is they may have went away for the Holiday week, but this is only a guess as it looks like they have not been active since 8/23.
And I looked at their postings; you're right they are invalid but that probably due to them not being on and not paying their monthly dues to be a sponsor.
I'm hoping that's all it is as I really like dealing with AA
