Anand,
You should take more care with your redaction; I was able to figure out one of the twitter users (and hence the rest) just by looking at the blurred image, i.e. less than 15 seconds work.
I was informed ahead of the blog post, public timeline is public.
There are limited options given that the information is on the public timeline. Next time, perhaps redact everything except the url. Maybe that would make it harder to find.
Not sure a redaction is even necessary ... Twitter is public and all parties posted that information in a public manner. Your resharing it doesn't make it any more public, although it may make it more popular.
Er... this was posted to a public timeline so everyone can find it anyway.
