Migrants to IJ, 2007

There have been first strike warnings issued to at least two LJers - one of whom had deleted the picture in question more than a week previous, but though it was completely inaccessible to her it was still on LJ's servers, and the other who had f-locked all her posts and posted age statements.

There's a summary by diachrony that explains it all and has the links in one handy place for your reading pleasure. Or torture. One of the two. Either way, there is discussion on exactly what this means if age statements don't mean anything and even deleting the pictures may not be enough.
