There are now lots of similarly named accounts showing up in Recent Badges.  I think they are effectively spamming in the Recent Badges space.

I advocate for immediate destruction of such accounts and broader network-level blocks as needed.

I would also suggest that perhaps recently created accounts should not show up in Recent Badges.  (Actually I don't really see the point of having this section in the first place, but then again I also don't really see the point of having badges in the first place.)
