[Telepathy] Bug 551911 - Make possible to block messages from people not in buddy list

[Vitaly Minko]

Regarding this enhancement: https://bugzilla.gnome.org/show_bug.cgi?id=551911

>I'm waiting for the new block API before doing it.

Did you mean this draft? https://bugs.freedesktop.org/show_bug.cgi?id=28423

It seems not to be moving forward. What do you think about implementing this feature using the current API as a temporary solution?
