I've been locked out of Google Adwords Keyword tool for well over 24 hours, for "Unusual activity". Apparently my searches ( just basic searches for "non-offensive sites") have been against their T&Cs and I may be allowed back in once I stop searching. (Goodness knows for how long).

Does anyone know how I can get back in? What is the point of the keyword tool, if not for doing keyword searches? I'm at a bit of a loss here!
