I have been wondering about this since I started on steemit.

I run a big community news network that has been running since 1995. It has over 60,000 pages of content and I quite regularly get right to be forgotten requests. As it is a standard web based system I can comply without a problem.

If I was editor of a steem/blockchain based network I wouldn't be able to comply.

I guess somewhere along the line, and possibly quite soon, a legal case will come up. Not sure how steemit inc will handle that - but I am sure the lawyers will be happy 😊
