[liberationtech] Twitter "reappearing" message documentation..

[Ali-Reza Anghaie]

It became "common" knowledge (read: oft-cited conspiracy) that
reappearing Direct Messages in Twitter were the result of an
investigation.

A few minutes ago it came up again and the EFF was mentioned but
particular citation could not be found. I figured I would ask here.

Do we have any real documentation or transcripts that indicate that
reappearing messages are actually indicative of anything? And to that
matter - why would compliance be broken in that way if it was anyway
(tipping someone off effectively)?

I'm just curious if there was any real body of work on this or it's
just become repeated speculation over time. Thank you, Cheers, -Ali
