@AmishRakeFight has captured my general opinions on the matter.
If you are in a public grid space, I think you are choosing to give up a degree of control over who comes in/out of it. This seems intuitive to me, but obviously isn't to everyone, given how many people freak the fuck out at someone "crashing" into their scenes in public places. (And before it starts, I'm not talking about the people who don't bother to wait or read for context of what, if anything, of note is happening in the area--that's annoying, and those people tend to be those who don't even bother to read for context even in scenes that are +Events or to which they have been invited, in my experience). There is a not-insignificant number of people who believe that they can declare any public area off limits to others once they start playing there. If that's the culture of the game, then it makes sense that staff involvement or viewing would be problematic, because there's the expectation that all areas of the game are essentially private space, first come, first served.
I am old fashioned and still ask all people in a scene if I can post a non-event log. Even for scheduled +events, I prefer to give people a link to the live log (for my own sanity I prefer to keep up with things in real time as much as possible) partially so that those who are coming late or need to wander away for a bit can still have the info at their fingertips and partially as a disclosure that the scene will be logged. I didn't care about my own scenes being posted for a long time--until I unfortunately experienced a bit of alt-stalking that was very unpleasant, and the running commentary on personal scenes with others made me feel very uncomfortable, especially since it was done in an accusatory way. So I have a bit of empathy there for folks that don't necessarily want all their RP all the time logged and /displayed/ publically.
I never autolog. But I am pretty much the only person I know that MUSHes that doesn't. To me there's a difference between private logging and public display. For some people the threshold is probably "anyone I don't know about/didn't consent to being involved is turning my private RP public" for others it may be anything goes but auto-log posting, with everything in between. I don't think there's a right or wrong answer to this, but I do think it's probably very important to be very clear about where that line is on /your/ game if you have one.
