[Haskell-cafe] ANN: Hackage Account Registration Changes

As some people have seen, a spammer has started to create accounts on hackage to upload fake packages, in order to use their package-descriptions for linkspam. We'll be working to clean-up the package-index from this spam, and the accounts have been disabled. Further, we'll need to decide on some long-term changes going forward to make this sort of abuse more difficult. In the meantime, as a short term measure, we have changed new account registration policies on hackage. Users can still register as before, but new users do _not_ have upload rights until they explicitly request them and are granted them by a human being. (This is actually how we had configured hackage to work on initial deployment -- we loosened things up for some years as the extra step seemed unnecessary). Apologies for the inconvenience, but this seemed the most direct way to stop the current influx of spam. Users with existing hackage accounts should encounter no differences in behavior. Best, Gershom
