There is such a thing as a quote tool, but whatever.
A minor (or major) banwave tends to precede any big release, although mostly if they're online. FF13 doesn't seem like the kind of game that would incite a banwave, except to those running the non-fixed version. In any case, we have not seen masses of people complaining about getting banned after playing FF13, so it's likely there's no banwave.
Interestingly enough though, warez sites seem to be suffering a systematic erasure of FF13 links. I've seen a dozen different sources (across several share sites and RAR configurations) all suddenly becoming dead links. It seems as if they're trying their best to prevent people playing the game before the release date.
