In short ... if you HAVE done that "Russian Meme" thing ... go read that info and, at minimum, change your password!
I'm glad that I'm a paranoid enough person that I almost never "do an LJ meme" without first reading the comments on the post (just in case other people are bitching about it!). In this case, every post of that Russian thing showed up as "no such entry" when I tried to read the comments on it ... which really made me suspicious, and led me into following the above trail of info.
Anyway ... thought I'd pass all this along here.
