By meta-censorship I meant things like removing the content from the website without a trace, so unless you look at the google cache, you have no idea that anything happened, and unless someone quickly makes a backup, you have no proof that it happened.
Leaving the notices "this comment was removed" on the page is precisely what allowed RW to make a nice screenshot about LW censorship. LW itself provided evidence that some comments were deleted. Providing a hyperlink instead of screenshot would probably give the same information.
Also, I am mentioning basilisk now, and I have above 95% confidence that this comment will not be deleted. (One of the reasons is that it doesn't get into details; it doesn't try to restart the whole debate. Another reason is that don't start a new thread.)

If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one.
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
