That might be so, but it's still a possibly identifying fingerprint.

Sorry, but only people who have never written HTML by hand could think that omitted </p> tags are a useful identifying fingerprint.

It can fit in with word choice, indentation, line length, etc as part of a personal pattern. But by itself it is as meaningful as saying "and".

I have 4 errors, 5 warnings...

So, do I, now. But it's the ISP's over-quote page, not the page originally posted.

Ok, my bad.
