You know what would be cool? If you could type a domain name in a post using a magic format that could be programmatically located, like [=mydomain.ca=][1w] or some other unique pattern. Then the domain name automatically gets obfuscated after the specified period (i.e. the [1w] part). So in my example, [=mydomain.ca=][1w] would automatically get redacted 1 week later and would then look like this: [domain redacted]
So its kinda like snapchat or a MissionImpossible self-destruct instruction on the domain name.
It would be easy to do, run a script run via cron to locate messages in the db with the magic format, test to see if the period has passed, then auto-redact it. Anyone _not_ wanting that feature would just type their domain some other way.
Not sure if anyone else likes that idea or not, but I guess I'm more the discreet type, I don't mind sharing stuff briefly but also don't necessarily want it permanently out there either...
