About a week go, I used the Aldib - Dallas server and was not blocked, then the next day I was blocked.
I switched to the Draco - Dallas server and was able to use craigslist, then the next day I was blocked again.
I switched to the Rasalgethi - Dallas server and was able to use craigslist for several days, then just a few minutes ago I was blocked again.
I switched to the Albireo - Atlanta server and that was blocked again.
This is the message I get (the email address changes on each subdomain of craigslist I visit).
