I have been with donhost over a year on their unix plan, and yes as mentioned they did used to close down accounts for offending files, bandwidth limits etc....However last year they implemented a new policy and only severe breaches get accounts closed, they now remove files that breach the policy and let you know.
Uptime is excellent, there has been very little downtme in the last year and support is usually relatively fast and good. Their control panel is also easy to use.
The major drawback is the price, since they cut the bandwidth limit i think it is badly overpriced.
