Craigslist technical contact - IP Ranges blocked

Hello All,

Does anyone know the best way to get connect to Craiglist technical
support regarding the blocked IP ranges. We are an ISP in Canada, and
since early this year we noticed that most of our IP blocks are blocked
on some of the Craigslist's servers. One easy example is finding any
items on Craigslist, hit reply, and gives an error "Sorry, something
went wrong", the web analyzer indicates status code 403 forbidden.

I understand that if individual subscriber IP could be automatically
blocked due to certain reasons by Craigslist, but I don't know why our
entire IP blocks could be blocked, even some IP ranges are never
assigned to any active services.

Did anyone have the encountered the same issue before, how can we get it



Erik, please contact me offlist with details (IP block, etc.). We'll shake the tree for you.
