Does CL Ever Unban IP Address

I would assume there isn't a permanent ban. If you're using DSL where you share a pool of IPs with other customers, wouldn't make sense for Craigslist to permanently ban them all and prevent innocent users from using it. Just my hunch.

I probably think its permanent. Same with accounts. Just tried to log into one of my accounts that got banned almost a year ago and still no go. Probably the same for IPs
