Some stuff will survive that, like a proper noun that doesn't translate in either direction and is given a characteristic misspelling, possibly combined with other hints. Sentence order will survive too, as well as higher-level structure. There are so many places in a document that is several dozen kilobytes large to hide bits that it probably impossible to ever be sure you've scrubbed them. Especially since it won't take that many bits to identify the source. Hiding the bits doesn't even have to be done via clever textual manipulation; it is a standard part of the intelligence game to make up entire facts with no basis in reality and then see where they leak out, then trace back. No amount of cleverness will save you from that.

Then your evidence translates into gossip.

This strikes me as a clever idea :)
