Hackage is flooded with old package versions reuploads

[kyra]

Hi, guys,

It looks old (and even ancient) versions of many packages gets uploaded 
to hackage over and over again in ever increasing amounts. The username 
of uploader for vast majority of these uploads is HerbertValerioRiedel.

While this is harmless I wonder what idea stands behind this?

Cheers,
Kyra
