I hate referral links. mainly because some can be malicious.
BUT, having said that, I believe Steemit should remain UN-censored. I believe in No censorship and decentralization .
We have the option of policing ourselves with down votes. If you don't agree with a post,then you have the option to comment and downvote it.
It's a fine line, and I think we need to be careful not to start censoring
It's not possible to sensor anything on the Steem blockchain -- the transaction is there no matter what it contains -- but it is definitely possible to control Steemit the frontend. We do need to be careful to treat Steemit the way it was meant to be treated, which is as you said, without undue censorship.
Removal of malicious referrals/URLs is not censoring IMHO. Those shall be taken down/deleted, preferably from the blockchain to prevent harm to anybody. The blockchain is the central place of storage, and has many interfaces today and will get more in the future. When fighting the harm in the user interface, this will not cause potential harm through user interfaces that are not that quick to adapt itself, or may never embed features to warn the user for URLs that are malicious.
