What about the folks who actually have the handles anonymous aardvark, anonymous banana, anonymous custard etc.?
Far better to simply make the date & time of each post immediately obvious. Then we have AC Aug 7@12:33:51, AC Aug 7@13:03:51, etc. ... or even AC@12:33:51, AC@13:03:51, etc, given that most threads don't last more than a day or so.
Each post is already timestamped with the seconds since the epoch, so this would be a simple change for ElReg to make. Would be easy to reference particular posts from non-AC authors, too, I ain't Spartacus Tue Aug 7 14:33:51 UDT 2018.
