BTC-e is completely retard on the ban issue.
Using bots and respecting their artificial limit of one query per second still can get you banned. I'm not fully against the ban, but the huge issue is that you get banned for every kind of access. This means you can no longer access the site, and the support email is a black hole. No email is sent telling the reason for the ban, neither how long will the IP continue banned. There is also the issue regarding dynamic IPs.
All in all, BTC-e please get smarter and change the way your ban behaves. Revoke the API key if you must, but don't act like a robber.
This also applies for every other kind of ban that is possible in BTC-e: the ban should block /only/ the action that caused the ban, not the fucking whole account for any kind of access.
