it's not possible to remove content from a blockchain unless you completely re-stream it as far as i know ... they don't have an intermediary 'cooldown' layer that keeps the posts on a separate server for x days before they're locked in so actually all your edits, all original and post-edits are there (thats as far as i understand because its an incorruptable ledger the whole thing is you can't edit it ... in theory , as long as there's enough nodes active , under some circumstances things might be 'taken over' by a kind of cartel if they join up thats why more nodes = better and compared to the 9000+ BTC has to keep its data valid i dont think steem has nearly enough .. thing is, people see witnesses and think nodes get paid by default or maybe they think it should be like that , but in fact its not, no one running BTC nodes gets paid just for running it to the best of my knowledge .. @abh12345 @smooth and yes 'at the discretion of steemit.inc , its their company and they do with the DAPP as they please but i think they shouldn't play all magnanimous frontface either, they're the biggest dumpers of their own coin and expect the plebs to fix it ... if i didnt like this thing i wouldnt be here but the tek is just too cool to play with
actual money (as promised on the sign-up page) instead of sticking money into it to be able to do something would be a nice bonus :D
