exactly. a five day vacation for the first offense of buying gil (and breaking the terms of the ToS) would definitely make most reconsider the "ease" of purchasing gil when they could lose their character. vacations for buyers works, plain and simple. actions against bots never will.
people dont want monitoring additions to the software, and rightfully so. the only actions SE can do, and should be doing, exists within their database, and would be a lot easier for some version of their STF to monitor and take actions against.
