It seems that someone has re-created AsteroidMeta:HomePage merely so it could be spammed. :-(
Should we simply keep deleting it ? Should we keep replacing it with a pointer to where it went: http://planetx.cc.vt.edu/AsteroidMeta/ ?
Hm, I don't know. Theoretically we should just add the expression to the BannedContent page, and rely on the automatic process do delete spammed pages.
