@woodenwookie what you're asking for is at the moment technically impossible due to the very nature of a block-chain

a block chain consists of blocks of data that can only be set in between two specific others and nowhere else, that's how the thing works, a chain of blocks that can't be altered :

hence : you can NEVER delete what you posted , i been going about this too several times, especially regarding the EU rules on 'the right to be forgotten' (which cost google a serious yearslong lawsuit already and they CAN delete)

EVERYTHING you post is stored immediately, there's no cooldown period

i asked @timcliff once (software-engineer / witness) he explained it was the intention as originally designed by @ned and @dan (the powers that used to be) scott and larrimer in case they wanted to audit

i still think its a bad idea to not have an extra cooldown layer in between but i'm not the boss here, lol

once something is written to the chain it can't be deleted unless the whole chain would be 're-streamed' into new blocks, omitting the data that one would want to remove (and i doubt they would want to go through the trouble of that ... unless, and thats one of my biggest fears for this thing, they hit a moneywall that's interesting enough for the E.U. to sue them
snickers but not funny

fyi
