I've written things about other people without their consent, figuring there would be a negligible chance anybody could guess who they were. But now I think that chance, while still not huge, is no longer that negligible.
(I've also written certain politically incorrect things, but as someone working in a non-humanities field over 4000 miles away from Harvard, and who isn't going to apply for a job in the US any time soon, and likely not anywhere else in the Anglosphere either, I'm not terribly worried about that.)
Searching Google for your username leads to a Wikipedia account with fairly detailed information which should be easily identifiable to people who know you personally, so if someone suspected your identity they could probably easily verify it.
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. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
