What do you mean?
As I understand it, witnesses have a position as mediator for the system and between system and users. And that would imply for them to be accessible for users, but in case they blocked someone, they exclude this user from getting into contact with that witness. And before you say: Well, there are numerous witnesses: What if all witnesses blocked that user? It's unlikely but not impossible.
Just a few days ago for example, you muted @bridgetoby. How is he now supposed to get in contact with you?
Hi @doodlebear. Thank you for your reply!
We understand and hear your concern. The witness account however is @blockbrothers and had not muted anyone and is a 100% reachable for anyone. Especially so because of the notifications app we released for free. Each member receives all mentions of @blockbrothers.
@bennierex and any single private entity of blockbrothers is free to use the steem blockchain as we (just like you) see fit. Though we do so with the utmost discretion and maturity. It’s one of the reasons we joined forces and set up a seperate account for witnessing and developping on the steem blockchain.
This way our personal accounts won’t interfere with the witness account.
I hope you can relate to the difference between the personal and the witness.
Which our witness @blockbrothers doesn't do.
Even more so, we have set up multiple ways for anyone to reach us. See our @blockbrothers witness post titled Ways of Interacting for all the ways you can reach us.
