Librarything has brought to my attention that its inferior competitor Shelfari has been spamming people. Whom Tim Spalding(the owner of librarything) describes (via another source as this):-
in the words of the well-known blog Gawker, "basically social networking rapists."
I've noted also that Shelfari has been emailing me a lot lately and its very annoying (and something librarything NEVER does).
Hopefully, shelfari will stop it soon.
