The information is still on the blockchain, it cannot be removed. Only access to it can be blocked by the website you use to 'read' the blockchain. Anyone with the skills can write software to read the blockchain. It is unlike Facebook in this regard.
Steemit and Steempeak however, as interfaces to 'read' the blockchain, have IMO exhibited Facebook-like behaviour by blocking certain content from being displayed.
Perhaps this is inevitable when there are vested interests (including fears) that come into play. Perhaps there is pressure being applied. The 'official' reason seems to be (from Steemit) that the 'hacking' violates T&C.
Yes I have found it on Steempeak. A overreaction on my part of Steempeek shows it a blocked but by clicking on the dots you can expand and read it. Nice one 💯🐒
